I like, that the knife is so easy to disassemble and to assemble. No special tools needed, no springs that jump away, no tiny parts that can get lost. Everyone can open it easily for cleaning and repairing purposes. This is worth to mention, because when we look into other OTF designs, you mostly see the exact opposite.
Thank you for that positive analysis. The only spring that could jump away from you is the lock return spring I suppose… But at least that one is easy to remember where it goes back once you found it again ^^

I love it. In itself AND its concept. I would like to a have the 3D printed version as a ‘cheap’ ‘toy’ to show people. The properly made item will be so collectible that not enough people will get to enjoy your brilliance.
Nice! Simple yet effective design. Have you thought maybe of long pins, from the hanle to half the length of the blade, locking in to the blade's slot both sides for stability? You could even ran them through the whole handle to create somewhat full tang (or more like half tang, if I could say) lock/support. Having the length of the handle, the four blade rail-supporters could be fixed, which will probably make the blades really steady when in place. Just a thought. Thanks for materializing the "double tanto" concept!
Jorge posted on FB a projected price of 400€, if the blade steel used is a premium steel that may help justify the cost in my mind but if they're using ordinary stainless steel or basic carbon steel I'd say it'll be overpriced for a mass production piece
This is not up to me to decide on my own. Currently the files are part of the R&D deliverables of what is of course a commercial proces and as such valuable. But something Jörg and myself can discuss with Midgards Messer (of which Jörg is also partial owner) once the production run is completely sold… who knows what happens :-) it is also important to note that the files are not for printing on FDM… and even with the SLS process a lot of post printing work was needed to make everything fit and slide smoothly. Not for the average ‘I am going to print this’ person (not saying you are). Thanks for your positive words and interest in the project!
@@zeroy yes it took extensive sanding to make everything fit well. This is because the clearances I drew are not suffiecient to make up for the tolerances of 3D printing.
I had an idea and would love your thoughts on it! In order to make the lock in the production version slightly stronger, would you be able to use the flat back part of the ramp side of the locking interface (this side ➡️📐), as another lock in itself? Effectively having it lock on both sides until the ramp is pushed down and out of the way? This would unlock and move both the round lock section and the “ramp lock” side with the same function. That way it locks and unlocks in one motion still, but provides a stopping point on both sides of the blade which would make it (in theory) 2x as strong. Love this design and think you guys are brilliant!
Thank you for the positive feedback and sharing your thoughts. The strength of the blade (or rather its stability inside the handle) really isn’t that much dependant on the lock itself being on one side only. As long as the tolerances between the blade and the engulfing grip portion are tight enough the play will be minimized. We ‘will’ have tighter tolerances on the lock itself though… The cylindrical portion under the ramp which actually moves through the hole in the blade. In the 3D printed version the tolerances are pretty large and also between the ramp and the cavity inside the blade. This will be much tighter in the real version which will stop the ability from the lock to slightly screw itself in the blade which is now responsible for the tiny amount of backwards and forwards play. Side to side play of the blade is also only a result of the fitment of the outer planes of the blade relative to the inside of the combined grip sections holding it. Hope this explains.
@@nirodha7028 thank you for your reply! This all makes sense and I cannot wait to see the final product! Very interested to see what blade steels you guys will offer for this when it is released! Definitely have to get my hands on one 🙌🏼

Just saw the video with Jorg, it would be amazing if you could locck it in the first position as well so that you have the option to have a full tang, as some people were complaining, that way you could abuse the knife more. Maybe its not worth it. But wanted to throw the idea in there! love the work!
i really admire the simplicity behind the mechanism. I am confused though, what would these knives classify as?

@@Furno52470 thank you for your enthusiasm! It is important to ensure you abide by local laws en legislation. Make sure you know you are allowed to own a set of these before ordering (once they become available). This is your responsibility. I’m in the process myself of figuring out how these clarify in my own country and even the enforcing governing bodies are puzzled by how to classify this set. So I understand your question all too well :-)
Well done on the demo, I've done demos on stuff and it's not easy. The only real problem that I can see with the design is when the blades are returned to their 'sheath' position. Aiming 2 steel knife points at 2 slots at the same time, especially at dusk or night, is really an accident waiting to happen. Maybe plastic guides that push out of the way when in locked position? Don't know, not my field.
Thank you. Yes it is one of the more difficult things to do with the blades. But having practiced myself for some time now it does get easier.. and is actually fun to practice. Note that quick deployment is much more important than quick re-sheathing with an item like this.
@@joaralvdal5717 initial testing promises good results :-) Go check out Jörg’s channel where he does a sneak peak test with one of the early production samples.
I Love it! My only question is why does it have the false secondary back edge instead of just keeping it at full thickness along the spine for added strength and rigidity like a real tanto?
This design is inspired by the WW2 Japanese Tanto which also featured a partial fuller and false edge. We also ‘need’ the fuller to stop where it does to engage with the ball retention inside its sheath in the opposite grip. Hope this explains :-) And don’t worry about strength. The blades will be made from high quality materials and the false edge won’t compromise anything.
@@nirodha7028 I have seen some videos on the sling shot channel but this is so awesome to see the internals. Will certainly be keeping a close eye! Thanks for the reply !
Nice. But what is that ball retention mechanism retaining? It looks as though it engages that groove on the other blade, but I'm not sure what it's purpose is. Or is that what pulls the blade out of the handle?
It is indeed responsible for ensuring each blade gets pulled out of its own grip and into the location where the lock can engage ‘before’ being pulled out of the grip of the opposing knife.
It would definitely not be a carry legal knife in the Netherlands. Our rules and laws are different from the ones in Germany. I am actually personally in the process of trying to find out if this set could fall under the category of collecting knives and if in that case it would be legal to own a set and have it in your house as part of a collection. I don’t want anyone to ever do anything illegal nor myself… So please educate yourself on your local laws and regulations.
Due to the importance of this question and because I do not want anyone to do anything illegal and get into trouble I would like to come back to this question. I have done some research and the answer is as follows: These will NOT be legal to carry or even own in the Netherlands. Any ‘folding’ knife which… in unfolded state is longer than 28 cm in total is considered a category 1 weapon. Also any folding knife with more than a single edge falls under this category. Since both those stipulations apply to this design the final product will not be legal to own in the Netherlands. Weirdly it ‘is’ legal in the Netherlands to own swords like Katanas or full tang Tantos. You are NOT allowed to carry those… but you can have them in your house when the owner is over the age of 18. You are also allowed to own double edged swords, bajonets and rapiers. Again…. Not carry them. Apparently the fact a Tanto (or even a sword) could be made to fold, then makes it illegal to own. The reason this is strange is because a full tang Tanto or sword will under any circumstance be a stronger weapon than a folding one. Unfortunately this doesn’t matter and the foldability combined with the size makes it fall into category 1. This means I will personally not own a set of these as I am Dutch myself. They are designed for the German market and will be sold in Germany. Their laws differ from the Dutch ones. The 3D printed prototype shown in this video and created for R&D purposes only is not made from metal, completely dull and is not a functional knife.
do not pin me down on it yet because everything is dependent on final material choices and a whole lot of things I don’t control… But Jörg in past videos has already mentioned it will be upwards of €600 for the set. Future blades which follow the same basic principle are not out of the question. We call them derivative designs in the industry.
@@AvimadyeOrunni hahaha about what? :-) It’s a collaborative effort by the way. So if we are really purist here: it is a German/Dutch engineering project ;-)
Imagine a double butterfly krambit knife w this design or different knife/spike mix up for two In one thought if u probably already thought this but hey ideas
imagine your walking home and a theif points a knife at you and demands your belongings and u pull out 2 knifed from a single sheath that thief would loose his mind
Where will we be able to buy these when they are mass produced? Also, are you considering stainless steal or tungsten for the handle and Damascus steel for the blades?
Interesting design for sure, what type of steel will be used for the blades? i asked Jorge but have not got a response, for the 400€ he quoted in his post blade material becomes important
@@MrMann703 As mentioned on FB: I think Jörg mentions the type of steel intended for the blades in one of the videos covering the subject, but I am not sure :-) I ‘do’ know that high quality steel will be used… without being able to tell you the exact kind at the moment. I will make sure to ask. As you can imagine we are in the process of back and forth with the factory to get samples perfected… so things are in flux. The intended steel for the blade isn’t though so again… give me some time to check up on it. Remind me in a couple of days;-)
I was wondering if you cold do a file for 3d printing or sls printing I would buy the file, and I also would buy a real blade. not to say the direct threaded holes would be bad. but I would enjoy the separate thread lugs incase you accidentally strip the threads. I believe this can be made cheap and it be really affective. mill the outer handles out of steel, laser cut the lock plate. mill the separator plate, use metric hardware to connect as well as the thread lugs so can be replaced incase of stripped threads, and make the blade in some way
@@stravvensnest3817 thank you for your enthusiasm! Since these will be produced in a limited amount the files are not for sale. Trust me when I say they will be built to the highest quality standards.
why not get rid of redundand tsuba/guard? use circular end plate to hold side pieces near the blade, then there will be no visible screws. i think it will look even prettyer while sheathed and it will allow to use any guard design
It is not redundant as it creates the ‘flesh’ in which the bal retention hub is positioned. Also a lower part count ensures less failure points. This design also greatly stiffens a portion of the frame which will get the grunt of the force of the blade when it impacts a target.
@@ninjaming the retention nubs that hold onto the fuller of the opposing blade in each grip ensure they stay in until they are locked. When you pull the blades into the lock inside their own grip all the force of continued pulling goes into releasing those retention nubs from the fullers and seperates them from the opposing grip (sheath). Hope this helps.
Sorry no. Not at this point in time. The files are part of the R&D process which is commercial in this case. As such the files are valuable and cannot be shared.

@@nirodha7028 Oef... that is honestly very disappointing. Have been following this knife for a while now :-( Is there maybe a possibility for selling them in NL without sharpened blades? I love the mechanism and the look of them. Thanks for the thorough reply!
@@YourComputerExpert yes it is a bummer. There is no ‘out’ to somehow make them legal in NL as they are defined now. A smaller version (which stays below 28 cm unfolded including grip ‘per knife’) and with a single sided edge would to be legal to own in NL. A smaller version is something we are already talking about…. So you might still be able to appreciate the mechanism from up close at some point in time :-) Keep following I would say. That way you will know when it becomes a thing.
I have done more research and things might be looking up. Category 1 speaks specifically of ‘folding knives’ which are longer than 28 cm in total and/or have a double edge. These blades do not ‘fold’ fold however they slide… and they also don’t slide completely into their own respective grips… Just roughly half way. So one can argue that these blades only ‘extend or shorten’ themselves but they never ‘fold’ into the handle completely… This means they might actually fall under category 4 which would make them legal to own as an adult in the Netherlands and keep safe in your house. This is NOT yet confirmed by legal counsil, but I am working on that. Will keep you posted!
What if you the tang of the metal a bit more space on the inside for stability and making the blade a little bit shorter like daggers, it would still elongate but it wouldnt break as fast while chopping or something like that 😅😂
Yes it allows the ball defend to travel with less resistance upto the point where you need it to grab the fuller. On top of that it matches a ww2 era Japanese Tanto design which I personally like the look of :-) So both functional and personal preference.
Dumb questions do not exist. But no unfortunately these files are part of the R&D process in a commercial sense since we aim to produce the blades and as such are valuable.
@@coIorsone do not pin me down on it yet because everything is dependent on final material choices and a whole lot of things I don’t control… But Jörg in past videos has already mentioned it will be upwards of €600 for the set.
PLEASE don't make this a limited design! or atleast make this la imited version in premium materials and then make a more mainstream one out of say 14c28n Steel, which is super tough and corrosion resistant while being affordable. The affordale version could be a bit shorter if it will make it more practical and economical to manufacture but keep the 14c28n steel as it's really popular in knife world and that way i think you can get this cool knife tech to more people.
Thank you for your enthusiasm! I am not the one deciding the strategy. Midgards Messer and particularly Jörg are known for their limited editions so I understand why they go that route. We never know what the future holds in store though. In any case I am very confident that between them they have plenty of experience to come up with a balanced approach between demand and numbers produced. Limited or not.
I have to thank you for this concept and I took it as excuse to make something from steel. So I have my own shitty version at home now ruclips.net/user/shortsF2kM3Dmr590 Looking forward when this will be on the market so I can buy proper one.
is it possible to lose the bolt? hear me out: the threads for those tiny bolts are 100% going to be the first thing that goes upon repeated disassembly for maintenance. if you were to replace them with fixed steel locator pins, and tasteful looking retainer rings which slide over the handle, the knives would have a much longer service life before breaking. also disassembly would be a breeze, something you'd do just to entertain people, not just out of necessity. this would also mean you'd maintain the mechanism more often. bolts suck in general, and tiny bolts suck more than large ones. please consider this idea. thanks

In order to make the lock in the production version slightly stronger, would you be able to use the flat back part of the ramp side of the locking interface (this side ➡️📐), as another lock in itself? Effectively having it lock on both sides until the ramp is pushed down and out of the way?
This would unlock and move both the round lock section and the “ramp lock” side with the same function. That way it locks and unlocks in one motion still, but provides a stopping point on both sides of the blade which would make it (in theory) 2x as strong.
Love this design and think you guys are brilliant!
Thank you for the positive feedback and sharing your thoughts. The strength of the blade (or rather its stability inside the handle) really isn’t that much dependant on the lock itself being on one side only. As long as the tolerances between the blade and the engulfing grip portion are tight enough the play will be minimized. We ‘will’ have tighter tolerances on the lock itself though… The cylindrical portion under the ramp which actually moves through the hole in the blade. In the 3D printed version the tolerances are pretty large and also between the ramp and the cavity inside the blade. This will be much tighter in the real version which will stop the ability from the lock to slightly screw itself in the blade which is now responsible for the tiny amount of backwards and forwards play. Side to side play of the blade is also only a result of the fitment of the outer planes of the blade relative to the inside of the combined grip sections holding it. Hope this explains.

This means I will personally not own a set of these as I am Dutch myself.
They are designed for the German market and will be sold in Germany. Their laws differ from the Dutch ones.
The 3D printed prototype shown in this video and created for R&D purposes only is not made from metal, completely dull and is not a functional knife.
Bro you can make twin Blade shinobi sword using this concept
How much would it cost approximately, and are u planning on coming out with different iterations?
do not pin me down on it yet because everything is dependent on final material choices and a whole lot of things I don’t control… But Jörg in past videos has already mentioned it will be upwards of €600 for the set.
Future blades which follow the same basic principle are not out of the question. We call them derivative designs in the industry.
💯🔥
@@b4zz3d59 thanks!
Nothing like German engineering. Would really like to buy one
Dutch engineering in this case ;-)
@@nirodha7028 Well well well! Ik ben verbaasd 😂😂
Well well well 😂 Ik ben verbaasd
@@AvimadyeOrunni hahaha about what? :-) It’s a collaborative effort by the way. So if we are really purist here: it is a German/Dutch engineering project ;-)
@@nirodha7028Just don’t hear much about Dutch achievements. Need to put more respect on that country ✊🏼
Imagine a double butterfly krambit knife w this design or different knife/spike mix up for two In one thought if u probably already thought this but hey ideas
imagine your walking home and a theif points a knife at you and demands your belongings and u pull out 2 knifed from a single sheath that thief would loose his mind
Where will we be able to buy these when they are mass produced? Also, are you considering stainless steal or tungsten for the handle and Damascus steel for the blades?
Interesting design for sure, what type of steel will be used for the blades? i asked Jorge but have not got a response, for the 400€ he quoted in his post blade material becomes important
@@MrMann703 As mentioned on FB: I think Jörg mentions the type of steel intended for the blades in one of the videos covering the subject, but I am not sure :-) I ‘do’ know that high quality steel will be used… without being able to tell you the exact kind at the moment. I will make sure to ask. As you can imagine we are in the process of back and forth with the factory to get samples perfected… so things are in flux. The intended steel for the blade isn’t though so again… give me some time to check up on it. Remind me in a couple of days;-)
@@nirodha7028 sorry, I asked on FB after here, I get tunnel vision when I see knives
@@MrMann703 I just had confirmation several high grade steels are still being considered. No definitive choice yet.
I was wondering if you cold do a file for 3d printing or sls printing I would buy the file, and I also would buy a real blade.
not to say the direct threaded holes would be bad. but I would enjoy the separate thread lugs incase you accidentally strip the threads.
I believe this can be made cheap and it be really affective.
mill the outer handles out of steel, laser cut the lock plate. mill the separator plate, use metric hardware to connect as well as the thread lugs so can be replaced incase of stripped threads, and make the blade in some way
@@stravvensnest3817 thank you for your enthusiasm! Since these will be produced in a limited amount the files are not for sale. Trust me when I say they will be built to the highest quality standards.
is there the way the print myself? Does the file can be bought from 3d sites or is it not up yet?
@@pakssmsjsjsks8596 nope! These will be commercially made and as such the files are protected IP.
why not get rid of redundand tsuba/guard? use circular end plate to hold side pieces near the blade, then there will be no visible screws. i think it will look even prettyer while sheathed and it will allow to use any guard design
It is not redundant as it creates the ‘flesh’ in which the bal retention hub is positioned. Also a lower part count ensures less failure points. This design also greatly stiffens a portion of the frame which will get the grunt of the force of the blade when it impacts a target.
How does the blade pop out like your another video?
@@ninjaming the retention nubs that hold onto the fuller of the opposing blade in each grip ensure they stay in until they are locked. When you pull the blades into the lock inside their own grip all the force of continued pulling goes into releasing those retention nubs from the fullers and seperates them from the opposing grip (sheath). Hope this helps.
Any chance I could get the 3D files? I would love to experiment with this 3D print.
Sorry no. Not at this point in time. The files are part of the R&D process which is commercial in this case. As such the files are valuable and cannot be shared.
@@nirodha7028 Aha good. I happend to be excellent researcher
Would love to get one, as long as the pricing is not too crazy. Greetings from the Netherlands 🇳🇱
Thank you for your enthusiasm. I have done some research and do not want anyone to do anything illegal or get into trouble. please be aware:
These will NOT be legal to carry or even own in the Netherlands. Any ‘folding’ knife which… in unfolded state is longer than 28 cm in total is considered a category 1 weapon. Also any folding knife with more than a single edge falls under this category. Since both those stipulations apply to this design the final product will not be legal to own in the Netherlands.
Weirdly it ‘is’ legal in the Netherlands to own swords like Katanas or full tang Tantos. You are NOT allowed to carry those (for obvious and justified reasons)… but you can have them in your house when the owner is over the age of 18. You are also allowed to own double edged swords, bajonets and rapiers (sharp or dull doesn’t matter). Again…. Not allowed to carry them.
Apparently the fact a Tanto (or even a sword) could be made to fold, then makes it illegal to own. The reason this is strange is because a full tang Tanto or sword will under any circumstance be a stronger weapon than a folding one. Unfortunately this doesn’t matter and the foldability combined with the size makes it fall into category 1.
This means I will personally not own a set of these as I am Dutch myself.
These are designed for the German market and will be sold in Germany. Their laws differ from the Dutch ones.

@@nirodha7028 Oef... that is honestly very disappointing. Have been following this knife for a while now :-( Is there maybe a possibility for selling them in NL without sharpened blades? I love the mechanism and the look of them. Thanks for the thorough reply!
@@YourComputerExpert yes it is a bummer. There is no ‘out’ to somehow make them legal in NL as they are defined now.
A smaller version (which stays below 28 cm unfolded including grip ‘per knife’) and with a single sided edge would to be legal to own in NL.
A smaller version is something we are already talking about…. So you might still be able to appreciate the mechanism from up close at some point in time :-)
Keep following I would say. That way you will know when it becomes a thing.
I have done more research and things might be looking up. Category 1 speaks specifically of ‘folding knives’ which are longer than 28 cm in total and/or have a double edge. These blades do not ‘fold’ fold however they slide… and they also don’t slide completely into their own respective grips… Just roughly half way. So one can argue that these blades only ‘extend or shorten’ themselves but they never ‘fold’ into the handle completely… This means they might actually fall under category 4 which would make them legal to own as an adult in the Netherlands and keep safe in your house. This is NOT yet confirmed by legal counsil, but I am working on that. Will keep you posted!
@@nirodha7028 That's awesome news, actually sounds promising! Thank you for keeping me updated, appreciate it a lot!
How can we buy this ?
Where is it sold?
@@TienNguyen-om4lz we expect them to go live somewhere in Q1 of 2025
Where can I purchase this!
@@dubaddicted88 not ‘yet’. But in time they will be available through Gogun (Jörg Sprave his shop)
What if you the tang of the metal a bit more space on the inside for stability and making the blade a little bit shorter like daggers, it would still elongate but it wouldnt break as fast while chopping or something like that 😅😂
What is the name of this knife and where can we buy it ?!
@@Jay-nr8ym ‘Instant Ronin’… planned to be available first quarter of ‘25
Where can I get this
@@tiklytahir not yet. We expect sales early 2025. Via Gogun.de and Midgards-messer.de
Wann kann man das gute Stück kaufen
Not sure yet. Jörg mentioned 2025 in earlier videos since 2024 is already booked with other products in the roadmap.
Is there a practical reason for the back edge? Personally I dislike both real an fake back edges I perefer a solid back when ever possible.
Yes it allows the ball defend to travel with less resistance upto the point where you need it to grab the fuller. On top of that it matches a ww2 era Japanese Tanto design which I personally like the look of :-) So both functional and personal preference.
@@nirodha7028thank you for the reply. 👍
@@nirodha7028excellent! Do you have an aproxímate price range? Need to know how much I have to save.
@@tonyfolin3589 not yet able to share… But might be a pleasant surprise ;-)
@@nirodha7028how far away is a release? Any possibility for an update?
How can I buy these? I reallly realllllllly want some
Can i get the 3d model to print?
牛逼啊，我想买
Probably a dumb question but there is no stl file available to print this myself right?
Dumb questions do not exist. But no unfortunately these files are part of the R&D process in a commercial sense since we aim to produce the blades and as such are valuable.
@@nirodha7028 I understand!
@@nirodha7028 Enig idee in welke prijsklasse dit mes gaat vallen?
@@coIorsone do not pin me down on it yet because everything is dependent on final material choices and a whole lot of things I don’t control… But Jörg in past videos has already mentioned it will be upwards of €600 for the set.
What’s the 3d printer files
PLEASE don't make this a limited design! or atleast make this la imited version in premium materials and then make a more mainstream one out of say 14c28n Steel, which is super tough and corrosion resistant while being affordable. The affordale version could be a bit shorter if it will make it more practical and economical to manufacture but keep the 14c28n steel as it's really popular in knife world and that way i think you can get this cool knife tech to more people.
Thank you for your enthusiasm! I am not the one deciding the strategy. Midgards Messer and particularly Jörg are known for their limited editions so I understand why they go that route. We never know what the future holds in store though. In any case I am very confident that between them they have plenty of experience to come up with a balanced approach between demand and numbers produced. Limited or not.
Yeah i know, i hope so cause this a cool design, i left the same message on jorg’s vid hopefully he sees it lol
I have to thank you for this concept and I took it as excuse to make something from steel. So I have my own shitty version at home now ruclips.net/user/shortsF2kM3Dmr590
Looking forward when this will be on the market so I can buy proper one.
Heheh looks like you had a lot of fun. Send some viewers this way if your short goes viral ;-)
@nirodha7028 will do my best, but I don't expect much reach with my poor channel 😂
@@JJFliesAndMakes hehehe you never know :-)
is it possible to lose the bolt? hear me out: the threads for those tiny bolts are 100% going to be the first thing that goes upon repeated disassembly for maintenance. if you were to replace them with fixed steel locator pins, and tasteful looking retainer rings which slide over the handle, the knives would have a much longer service life before breaking. also disassembly would be a breeze, something you'd do just to entertain people, not just out of necessity. this would also mean you'd maintain the mechanism more often. bolts suck in general, and tiny bolts suck more than large ones. please consider this idea. thanks
Hallo Nirodha, ich habe selber auch einen Prototyp aus Holz gebaut, aber eine andere Mechanik verwendet, vielleicht machst du ihn dir ja mal ansehen :) : ruclips.net/video/Fal0uJDrPkE/видео.html
Thanks for sharing. Looks good! Clever little lock mechanism you made.
I'm very pleased that you see the video and over your response. :)@@nirodha7028
@@nirodha7028 Ich habe einen weiteren Prototyp vom Doppelmesser gebastelt. ruclips.net/video/g82wiqrsHII/видео.html
Vielleicht magst du ihn dir mal ansehen, auch wenn dieser sich mit dem anderen ähnelt ;)
@@wiebremen4160 also looks cool! I wonder if you can somehow make the grips narrower above and below the blades… maybe for a V3? :-)
@@nirodha7028 Thanks for your answer. I plan to make another prototype using a different material (this could then push the dimensions even further to their limits).
. (about "narrowing the handles": The disadvantage of this mechanism is that the inside blade have to be higher than the seen blade-part... but in the other dimension they are quite narrow. So I think that the shape here is already final.)
So You Stole That Idea From Joerg Sprave! I Hope He Sees This!
Hahahah… click the link to the video I made together with him. You can find it in the description of this video :-)
I think you will find the truth is much more positive.
@nirodha7028 Okay I'll Check It Out.
Its not full tang and made of plastic. Talk about a junk ass coloectors item. I purchased the chinese version i saw in the sling shot channel. Its full tang and a harder steel then your expensive garbage. Why should I buy an expensive paperweight?
@@SuperFGeeT hahaha this prototype is indeed made of plastic and is not for sale. We are working on production samples and in fact my latest short shows you a preview. If you don’t like the design, then by all means don’t buy a set once they come out :-)
Are you going to release STLs?
No sorry. Not at this time. The files are part of R&D in a commercial process since we aim to produce and sell these. Therefor the files are valuable.
