I don't make knives nor will I; but I appreciate these videos and the effort put in by all involved

Love watching your stuff. Learned so much about steels. Would be awesome if you met Jay from Pew Science and did a interview about Suppressors and there steels. You could discuss inconel, titanium, new suppressor alloys that are coming online, 3D printing (sintering) and a lot more. Your two of my favorite people to watch/listen to because you want to help people and do it in a objective scientific way. Great work keep it up.

I love these I hope you will do more! Would love to hear your thoughts on Vascowear. If I am not mistaken I think it is similar to Cru-Wear. I used one of Geber's folders in it for years of fairly heavy use in industrial plant maint. and never found anything better. Whoever did the heat treat for Gerber nailed it.

Thanks Larrin and Malachi!

Definitely my favorite of the ultra high edge retention steels. I would say 15v is the only one with better feedback during sharpening, but i get a bit better edge retention from ASP60. Great steel; i hope to see a lot more of it. Edit: that T15 comparison shot is wild.

Are you talking about 15v with the big brown bear heat treatment protocol? Do you know how his protocol differs from standard protocols?

Very interesting info and explanations as always, thanks a lot!

I own a coustom knife in Vanadis 23, the steel has a really good edge retention.

I'm incapable of working with these steels as a bladesmith, but these videos are still very interesting to watch, thanks for all these videos and explanations Larrin!

I bet you could work with them if you wanted. It would just be more work

@@KnifeSteelNerds how do highly complex steels forge tho? Especially in a charcoal forge, in a very traditional setting... From changes in carbon content (be it loss trough oxidation, or carburizing in the fire...), to high changes of temperature, and probably tiny hot working ranges. Also, i don't imagine traditional ways of heat treating, such as using the forge or a bed of hot charcoal (wich is surprisingly even and accurate compared to using a forge) would be fitting for such highly alloyed steels... I personally focused my work on exotic alloys and damascus, like with copper based alloys that will quench harden, or offer interesting/beautiful results.

I think high performance steels are more for stock removal and not forging

Using a furnace for heat treating definitely makes it much more viable

Lovely

Oo yeah

The goods as usual. Does VG-10 have any hot hardness qualities at all with its addition of Cobalt even though it lacks Tungsten?

It does a little bit

Does this cover collapsible batons as well?

Can't wait for 100% pure Vanadium Carbide knives, it'll be so epic and easy to sharpen :)

PM60 is the version by Scana, right?

@@KnifeSteelNerds I've read that PM60 has even considerably more W and a little more Co and Mo than Vanadis 60. What does that change? If it does at all?

The rumored compositions are a bit murky, I agree. I wouldn’t worry about small composition differences, personally. They are still in the same “category” of steel.

@@KnifeSteelNerds Thanks very much. And a huge Thank You for everything you do for our knife nerd community. Both of your books are absolutely amazing, more capturing than a thriller - well, for someone like me at least. 😉

If I wanted a knife that had a very high polish, a mirror polish. What and it’s a pocket knife what steel would you recommend?

Something without significant amounts of vanadium like AEB-L or CPM-154.

The more wear resistant, the more it resists scratches… obviously, but that means the grind of polishing a harder knife pays off a bit more.

70 is the highest HRC I’ve heard of… have you (or anyone) done any modeling of the theoretical maximum hardness for any “steel” composition? What is the highest HRC achieved in practice? Thanks, Dr. Thomas.

I can’t say I know the exact limit but somewhere around 72-73 Rc. The Rockwell C scale technically stops at 70 though the tester will still read higher.
