That looks great. I’m sold - kiddo gets one for his 18th birthday next month. He’s occasionally cut himself with blades - something less sharp would be great. He hasn’t needed stitches yet but he got pretty close recently.
@@Pippy1 You’re saying you can’t learn how to use tools safely without at least initially injuring yourself? I don’t agree with that at all. But that’s also not really relevant here. When I said he got pretty close to needing stitches recently, I mean that he cut himself to the extent that he almost needed stitches for the injury.
@@gf2e I guess you’ve never heard that a sharp knife is safer than a dull one? If he knew how to properly use a knife he wouldn’t cut himself as often.
Ive been using a Slice blade on my Gerber EAB for 6-7 years now. Works great! I also have the package opener. It is fantastic! Doesn't gunk up with the tape residue like the steel blades. So that's a bonus!
Hardness is an interesting property. Kind of counter intuitive sometimes. Essentially, slicing is penetration of a surface. Hard materials would penetrate other materials, generally speaking. Sharpening can make a material more capable of penetration, for a set given hardness. So you have two phenomena working under the hat of "cutting". You can get a material that is less sharp and more hard to do a similar task. For the past 5 years I've been working as a physicist at a lab, growing CVD diamonds. It's quite amazing to see how a tiny piece of broken diamond can carve into anything. And diamond "knives" can get crazy dangerous.
@@lastbesttool Cutting is above particle level, as it is an act of deformation rather than a change of the material's properties. On a microscopic level, bonds between the material's building blocks are stretched until they break. It's as simple as you can imagine from everyday life, it is almost entirely mechanical. At the atomic level, metals are atoms that stack on one another, and they are electrically held in place. This makes metal atoms prone to "slide" on one another, which makes them forgeable. This is also what limits metals' hardness. Ceramics, on the other hand, are built entirely differently. Diamond for example is comprised of tiny carbon atoms that are tightly connected to other atoms via strong bonds, and every movement of an atom is repelled back by its neighbors. This is essentially the science behind diamond's hardness. The structure is very resistant to penetration. This structure is however the reason behind diamonds' brittleness, as opposed to the high toughness of some metals.
Alright I'm hoping you can help me out here. I've been looking for a video of yours where you're talking about different kinds of tape, strapping tape in particular, and after an hour of searching I've still not found it. I could have sworn it was the overland minimalist video, but I was mistaken. If you know the video I'm referring to, I would be very grateful if you could share it with me; I'm losing it over here man
They definitely don't work on some of the thicker boxes that get used at work and inevitably annoyed all the employees. Especially since we had the auto retracting versions they would just retract themselves. The worst was trying to take out the copper staples in boxes, they were terrible for cutting those out and you always had to rip them out with pliers.
Seem pretty good. Fabric, paper, cardboard, rubber, burlap, etc. I don't think they have the full blade reach on tougher materials like high quality metal shears, but for things that should be cut, these cut.
Blades that don't fit into normal knives, so they're proprietary that aren't as good as metal blades in just about every way? And they break stupid easy? Pass. (Edit: $119 for 24 blades? What a joke)
I doubt it. I'm kind of a serrated blade hater though. But I've never had any issue with a normal blade on boxes and don't want to mangle them up with sawing. Might be fine if it stays sharp like they say. Normally serrations dull quickly and resharpening then is a nightmare.
@@commentsonthetube14 yea I hate serrated blades and I received a new bench made I think it was the bugout for Christmas and it had half serrations on the blade. But anyway I have to cut so many boxes in appliances I’ve got to wear I keep the Milwaukee fastback box cutter on me at work.
Very interesting and cool to see different ideas, but even if they stay sharp longer than metal blades I can get fifty metal blades for the price of two ceramic blades. It’s cool though if you really want/need the safer blade style
it is an inexpensive brand on Amazon called Cool Hand. They make several models and the build quality for the inexpensive price is impressive. There is a metal liner lock so they do show up on TSA screening. Here's a link to a similar model since the one I showed is sold out. amzn.to/3FMOHoQ
The problem is that as a material gets harder, it also gets more brittle. Hardness is a great quality in things you want to stay sharp, however every material has its limit. Not only is it way harder to sharpen harder materials but it also means that the sharpest point is the weakest because it's thinner than the main body. Even though his strength test wasn't the most scientific, it did show the steel was stronger and likely more able to hold a sharper edge. The dullness might not just be for safety but a limitation of the material and manufacturing itself. I'll bet slice has found the optimal edge radius (essentially how sharp the edge is) so that the blade doesn't break at the point. It probably wouldn't be practical to sharpen it further, however you could always grab a diamond grit stone and sharpen it more if you really wanted. It's not a difficult process and the stones are only about $10 a piece.
The kitchen knives are a totally different approach to sharp ceramics. They are thin and very sharp. These are thicker and adequately sharp. The Slice blades would do well with vegetables but I think they would struggle with meats, especially since that is one of their features.

Hes not gonna learn if he doesnt cut himself and realize theres a certain level of respect u need with blades

@@gf2e that is exactly what im saying. Not every tool needs something like that but not every tool is as dangerous as a knife
@@BryceKimball7.3 I definitely have heard that before. But the argument here is that these blades aren’t dull. They’re the optimal sharpness.

Thanks for the video. Win goes to the snap-on plier🏆. I prefer ceramic sharpeners to ceramic blades for my needs.

Fascinating! So when cutting, what is actually happening at the atomic level with the forces involved? How are the molecules separated? Thanks.

Interesting concept! I went over and bought a couple of these to try them out. Thanks.
Kyocera makes some really nice ceramic shears and kitchen knives as well. Covert ceramic razor blades are also a thing.
Hello again Doc
Thank you for another Great Video 👍
Great timing! I was looking at those Slice ceramic scissors on Amazon a few days ago.
i wonder how SLICE does with stripping insulation off cable?
Yeah..get more of that green thing.! Happy Festive season mate. Warm greetings from Australia.
Power of edge geometry
I've been curious about those for a while
Ooog proprietary blade sizes.. this makes the "ooh i may buy" drop considerably
3.48 aww man…that’s the whole reason why i’m here :(
anyways i like the second knife in the video
Curious how those thread snips work on braided fishing line. That stuff can be incredibly difficult to cut cleanly.
Cool but steel works just fine.
i had mini slicer and found out it didn't fit for box opener, but I will try out that rounded corner box opener
Way cool stuff Doc.

Thank you Doc! I have this Boker Pocket Knife, it's amazing. Which item did you recommend to buy?
Whats it do to romex sheathing?
I think automatic open scissors used for sewing
Sewing would be a good use. They work great on fine precision cutting.
They definitely don't work on some of the thicker boxes that get used at work and inevitably annoyed all the employees. Especially since we had the auto retracting versions they would just retract themselves. The worst was trying to take out the copper staples in boxes, they were terrible for cutting those out and you always had to rip them out with pliers.
I don't think I've ever been able to cut through a staple with a box cutter anyway...
Awesome video those are pretty cool! I’m curious though, how do they do when cutting fabric?
Seem pretty good. Fabric, paper, cardboard, rubber, burlap, etc. I don't think they have the full blade reach on tougher materials like high quality metal shears, but for things that should be cut, these cut.

Would the serrated blade be better for a box opening blade?

Ya for kids and stuff it's probably alright butnif their blades don't fit in my box cutter I'm not really interested
👍🏻🔥
Thanks for watching.
The real question is does it open Milwaukee tools incredibly ridiculous plastic packaging

What brand is that pocket knife!!? 2:47
If I'm not wrong, it's a Boker. 👍🏻

@@lastbesttool I have exactly the same knife made by Böker 🤔😱
I feel like I'd buy some blades if they made them properly sharp like that folder. I don't buy this dull is safer nonsense.
What about trying one ?

I already tried to use then in professional kitchens… didn’t work at all.
They are sharp, but waaaay to brittle to being reliable
The kitchen knives are a totally different approach to sharp ceramics. They are thin and very sharp. These are thicker and adequately sharp. The Slice blades would do well with vegetables but I think they would struggle with meats, especially since that is one of their features.
