I have a drawer-full of 'folders', I pick one, carry it a week or two, then change - no real favorite.
Here are some larger ones I purchased at estate sales this summer:
Left - Edge Brand - Solingen Germany (stamped 160)
Middle - Wildcat Brand - Solingen Germany (stamped B47X)
Right - Homemade Skinning knife
*All have 'horn' handles. The two German knives have edges you can shave with.
Left - Cardinal Cutlery NYC
Right - no markings ( may have fallen out of a UFO? )
