Two Primitive Tribal Knives

This is a set of primitive treble knives consisting of one 11" bolo style blade with heavy grease on the blade. There is a square box etched into the ricasso ending with a 4" carved wooden handle, the scabbard is wood two piece, with leather keepers, looks to have had 4 more of them at one time. Great detail has been put into the pattern on the surface with the belt hanger. The second is a 9" Kris style blade heavy with grease, no markings on the blade I see, 5" handle, loose on the knife. The scabbard two hammered copper bands with the toe band missing. Nice set of primitive knives.
