I keep wondering what happens when you make a blade with two different materials: say one for the edge, another for the rest.
Obviously there are laminated blade out there, but that's not really what I have in mind (although some of the problems might be similar).
I've heard of a knife with a titanium blade and a tungsten carbide edge. Has anyone here ever used it?
More typically you could use two different steels, like a big knife with a very hard steel on the edge and a shock steel for most of the blade (so you can chop).

I went to a knife store a while ago and I remeber seeing a knife there that had two different steels. i don't quite remember the maker, but the knife was sandwhiched. The blade had a middle peace of Japanese Blue Steel, I think, sandwhiched between two pieces of one of the AUS or 440s, i'm not to sure. All I know is that the knife was one of themost beautiful, strong, trustworthy, and expensive creations I have ever seen.

Yes, absolutely. In fact, Warren Thomas is the same guy who makes Ti blades with tungsten carbide edges.
Has anyone actually tried any of these?
 
There are process found in forging blade with two different materials (soft and hard materials) call "Sanmai", and "Warikomi". I believe its found in traditional japanese blades, and it works as much as similar to edge hardening methods with single blade material.
 
RN0601: That's just one of the ways to make japanese blades and swords.
I've seen another way where they make a hard carbon steel edge with a soft core by folding the harder steel into a V shape and then pound the soft core into the blade. The V shape is the edge and the soft steel would be the core.
Yes, there are laminated blades (like San Mai) where you sandwich a harder blade with two softer material on the side.
A Frost Mora or a Cold Steel Master Tanto San Mai would be the example.
 
Clayth, I never stated it was "only" method which japanese blades are made. I've only stated a example of process allowing usage of two different materials. I really didn't mean to confuse anyone by stating two methods. By the way, method you've described is "warikomi" process isn't it? I'm not too certain about it, but if you know more, let me know. I'm really interested in topics such as this.
 
If you look to Mike Snody or Brad Duncan and their work you will see they have a process fusing Stellite and Steel. Stellite for the cutting edge and steel for the remainder of the blade. Very "cutting edge"
