It's always interesting and always going to be contentious as to what people regard as 'traditional' materials, but that's what makes a forum worthwhile-debate.
Simply because 'x' was not used decades or centuries ago clearly does not debar something from becoming accepted in the traditional knife world. Otherwise, there would never have been any change or evolution, flint fixed knives anyone?


Moreover, due to globalization and a scarcity of materials, different materials may become accepted as other become unavailable or even unethical for some. I think few Americans realize how controversial and unacceptable the use of ivory has become in many European countries. Ebony and Rosewoods appear to be becoming rarer and much more costly than they used to be, large scale felling of forests, lack of replanting. This may in some sense explain the use of Zebra Wood or Osage Orange on current traditional knife scales, both these woods look very attractive and seem very durable-an ideal combination. But no, you likely would not find them on knives a century ago, because there was no need for them or no awareness or interest in alternatives.
Currently, a lot of makers & customers are showing interest in Camel Bone, or Giraffe. It aint traditional I suspect, at least not in America or Europe - probably in Arab or African countries obviously. Yet there is a vogue for it, it takes dye differently, seems harder than Bovine bone and seems to be gaining ground. Ram's Horn is a very traditional material in Europe (excepting Britain) but that too has caught the American eye and is well received, but you would not be likely to find it on offer in catalogues from a century ago etc..
Material is also very pattern sensitive, and that's another consideration in all this. Yes, I agree with an earlier poster, Sodbusters look odd to me in jigged bone. They, or work knives like them, were usually wood or delrin, but it's largely an aesthetic prejudice. Convention can be based on this too.....
OK, what are my likes?

Stag, Jigged Bone, Smooth Bone, (Bovine, Camel) certain woods, Horns, Delrin, certain acrylics,Micartas.
My dislikes?


MOP/MOT, Metal handles esp Brass..,Abalone faux or real, faux woods, Carbon Fibre, Cell due to fear of its metamorphosis but it can look great, weird colours of stabilized woods, blue knives....Gum fuddy
