Looks like a typical finnish puuko design. If its a wood handle probably some type ofsofter wood, which you cantell by the weight ofthe handle.Is the handlevery light in weight.They are a little too far north for the typical exotichardwoods which other people use. If horn then moose or reindeer. All those nordicknives have pretty good steel even the cheap oneswith the laminated steel blades which those guys seem to have some sort of corner on.I have always been impressed with their knife steel as its very workable and can be sharpened real easy though it does tend to rust a little easier which is true of most working knives. Hope it helps.

edit: the handle is probably curly birch, I have something similaron afillet knife I have, just didn't know the name of the wood. take care.
