I’m not sure working on a pre-hardened piece is the correct way. using that cutting disc especially where the edge would be had changed it’s hardening values probably for sure. Working on a soft metal to begin with is 1, less machinery wear and 2, twice as fast shaping results, and then hardening to actually achieve that hardening value was shown on the blade. Beautiful work of art!!!
Actually, 58 hrc is pretty high and the blade being heated by that belt grinder and the disc might as well compensate the tempering process, though still, lots of unnecessary wear for his machines 🤷♂️:)

Bog Oak was a beautiful choice and loved the various tools to make the tang holes and perfect shape. Next a 270mm Yanagiba, and a 165mm Nikiri?? Always a real pleasure to watch your vids. Thanks for all the great work and sharing!!
No heat treat? At 58RC you probably lost a couple of hardness points from using the angle grinder, as they create a lot of heat. And depending on how how it got from grinding the bevels as well. Using a jig, and not freeehand, you can't feel how hot it gets. Also probably introduced some stress/uneven grain. I mean looks nice, but not sure about what's going on inside that grain structure, edge retention, and hardness as a result...
i think thats why he left a good chunk of metal to be taken off by the grinder near the cutting edge. the rest was cut directly on the lines. a minimally softer spine wont hurt anyone. the edge itself should be fine with the 3cm he had to take away with a belt
@@ShannonSouthAfrica i say rudimentary because he is using fairly primative tools - just look at his home made belt sander. Its very basic. Im not insulting him - hes working with what he has and does a spectacular job. Id just like to see what he could do using good tools.
The time is currently 03:00 Midwest time. I have scrolled so far, this is the last video in my recommendations. I am so tired. I have only been scrolling for an hour, but my body will not fall asleep. I hate nights like these.
Awesome crafting, Im waiting your videos and it's a real source of inspiration ! Just a question in minute 05:32 you put the knife in a liquid, wich liquid is it please ? what is the purpose to do that ! THANKS
Awesome work man. I love the way your handle looks like. Classy and good contrast. I wish to ask you for the specs for your belt grinder... In case you build it or if you could give me some tips or general schetch I could use if I would like to build something similar :)
like many other knife-nuts in the comments, i've got many questions about this impressive piece. i'm curious about the steel used, whether it was left at 58HRc, and if the knife is in fact zero-ground from a high-sabre?! if it were indeed zero-ground, that would explain the relatively moderate hardness, perhaps - it would ensure that such an extreme edge bevel wouldn't be prone to chipping? all these sorta questions.
Did i miss the part where he heat treated the steel so as to have some semblance of a rockwell value at the end? Looks nice , but I’m a skeptic on the edge-ability of that steel now.
J F it was prehardened before he started working the metal. It is a viable option but you have to really be careful not to get your metal hot close to where your cutting edge will be. It’s used a lot in really thin kitchen knives due to their ease of taking a warp during heat treat and quench. It’s not what I do but I know a few that do it this way.
mrskeet270 all that grinding completely ruined any temper that steel had before though. Nice looking piece but by no means will it hold an edge after all that

Yeah, probably the hardening of the blade is a totally mess... But for some photos, it's very good
Thought is not a pre-hardened steel. Look at the steel plate!

Thai Pham it says 58 hrc ，how ever this knife had no forge or heat treatment
Neriya Yadai 58 is really soft for kitchen knife 😢
It is beautiful precisely because it is simple. It is the elegance of simplicity that makes every detail stand out.
I have never seen such an amazing degree of precision with an Angle Grinder!
go check out Freerk Wieringa. He is so scary and precise with an angle grinder.
you aren’t supposed to use it on the flat face tho :/
I'm lucky to have all eleven of my fingers left.
I love the blade shape

Так держать!
Нож ладный получился!
А без бряканья музыки,с Реальным Звуком видео просто супер,давно с таким удовольствием не смотрел!
Так и есть!!! Почти весь канал такой!
What a simply beautiful kitchen knife, I really like the aesthetic and shape. Great work Koss!
That has to be one of the most beautiful knifes I seen made. Would love to own one you make.
Nice piece of art. Btw: The continues grain in the handle. This kind of details are what good knife makers sets apart from the others.

Очень приятно слышать как работает инструмент, слышать как происходит процесс изготовления. Спасибо!
Beautiful knife! Good job!
Thanks for the good video.
Such a beautiful blade and handle, mate.
Beautiful job
No respirator or pushstick?
Why i spend all day watching knifemaking videos?
I love the black color so much
That's a beautiful knife.
Класс!👍 очень шикарный и красивый кухонный нож получился!
Теперь еще футляр для хранения надо)
Very very nice job ☝️💯💯👊🍻
What about the heat treatment and tempering?
the steel came heat treated at 58hrc
@Naikan Naikan it's hard enough for sure. Just not ideal. If you sharpen regularly hardness isn't much of an issue.
Koss, пожалуйсто скажи чем ты обрабатывал(помазал) нож на 5:03 минуте?
Love watching you work beautiful craftsmanship 👍
Какая марка стали, если не секрет?)
Didn't you overheat the steel by cutting it with the angle grinder?
i think thats why he left a good chunk of metal to be taken off by the grinder near the cutting edge. the rest was cut directly on the lines. a minimally softer spine wont hurt anyone. the edge itself should be fine with the 3cm he had to take away with a belt
You do fantastic work with such rudimentary tools. Id love to see what you could do with good tools ! . Youre a true craftsman.
How are his tools rudimentary? I know nothing about tools, so please revert.
@@ShannonSouthAfrica i suggest you look up rudimentary in a dictionary.
@@aitf99 I've got a degree in English, so I know what rudimentary means... What I mean is what is so rudimentary about his tools?
@@ShannonSouthAfrica i say rudimentary because he is using fairly primative tools - just look at his home made belt sander. Its very basic. Im not insulting him - hes working with what he has and does a spectacular job. Id just like to see what he could do using good tools.
@@aitf99 Again, I barely know how to operate a standard hammer, so I can't tell the difference between rudimentary and advanced.... lol
Однозначно шикарная и достойная работа! Приятно смотреть.
Nice craftsmanship!
Beautiful as usual.
I feel like this is how machines were created… Somebody just dreamed about someone doing just this and somehow fast forward it X10 in their head.
Nice knife
wonderful !!!
Wow! I definitely plan on making one of these 🍳
Just awsome
Cutting edge of perfection

I am so tired. I have only been scrolling for an hour, but my body will not fall asleep.
I hate nights like these.
Very nice.
I would however highly recommend a slimmer cutting disc, I use a 0,75 mm (or 1,0 mm on occasion) and it cuts like nobody's business :)
Fantastic👍👍
I like the use of a the sawzall blade. Think I might use that myself this weekend. Nice knife!
Jigsaw blade
Sorry if this is a stupid question. What liquid you have inside that container where you put the knife and come out darkened? Thanks
0:45. Good on you mate!! Nice safety shoes. 😲✌
What is wrong with his Australian safety boots?
very cool
Awesome crafting, Im waiting your videos and it's a real source of inspiration !
Just a question in minute 05:32 you put the knife in a liquid, wich liquid is it please ? what is the purpose to do that !
THANKS
it's ferric chloride for blade etching
@@Koss-channel humm thanks a lot for your answer I'll use it for my next blade
That's what I call safety footwear! 🤘🏼😀
Love the knife saw blade, never saw it used that way, great idea.
Lovely job !! Very beatiful piece !!
It's just AMAZING🎉🎉🎉🎉 I'm cooker .I but one of your knife for testing in real condition in my kitchen!Peace Vincent
What’s the name of the jig you use when grinding at an angle at the beginning. Wonderful wok.
great work...👍👍
Such a unique skill you have. Congratulations dear bro..
Very nice blade! Love the handle design.
Adding tooth to the tang is a good idea, nicely done. Handsome looking unit.
Thanks for sharing your craft
Cheers
A beautiful item made via small, focused changes. 👍
Awesome work man. I love the way your handle looks like. Classy and good contrast. I wish to ask you for the specs for your belt grinder... In case you build it or if you could give me some tips or general schetch I could use if I would like to build something similar :)
Awesome video ! I enjoy your videos !
really like the handle simple design but elegant nice job
excellent job!
2:01 what is this machine? how name this¿ I wont buy something like that pleas for help ;)
And sorry for bad english ;/
its belt grinder, you can watch how I made it - ruclips.net/video/JICQOX9VUO4/видео.html
Thank You! Ofcourse i watch this video and then maby i dont need buy it i can do this by my self ;)
or maby only try :D
Belt sander
素晴らしい仕事ですね。
Impresionante obra de arte...enhorabuena amigo....tiene usted Nivel Dios.....Un saludo cordial....
What acid did you dip the blade in to get the rough top?
Is that iron chloride for colour treatment?
very simpele yet VERY Beautiful
*Great job!*
Beautiful
Hey man great work not sure how I missed this channel but I'm glad I found it.. Martin

Really nice piece
What kind of paper you use..as what I know once grinding on metal will hot and paper will burn..but what I see the paper not burn
5'30 What substance are you soaking in?
Loved it!
Beautiful knife. What is the length of the blade? I have a similar knife but the blade appears considerably shorter than yours.
Я хочу такой же!😁 Отличная работа!
It is like convenient food

What did you use for the handle finish?
Absolutely beautiful. Wish i have a knife like that.
That handel! Can u tell speks size on that handle?
Is this a good knife design for meat prep?

Satisfying.
No distal tapering at the spine?
So fancy
Excelente! Like👍
Wow that guy moves quickly.
