Carbide

[Lampman]

I am a new member, this is my first post.
Don't want to seem dumb, has anyone ever tried to laminate a piece of (very thin) carbide between two pieces of steel?.
Or some other extremely hard substance.

carbide is way to brittle for a knife. it chips super easy and having it thin, it wont take much.

I think Warren Thomas has and maybe still does.

Carbide would be good as a coating. It will improve the resistance to friction and a lot of other things that I'm too tired to translate, sorry.

But a blade fully made of carbide would break to impact, and a knife with a carbide center, as I think you mean, wouldn't be a good idea. I think a soft core or spine with a harder surrounding would be better.

As for carbides, when use in coating, are not even a "bar" but small spheres in a metallic matrix, such as nickel.

One of the Benchmade Emerson (CQC7) models had a titanium blade with a carbide coated edge. cutter17 is right: Warren Thomas does still make knives with composite blades, some with carbon fiber overlays and some with carbide coated edges.
