“Warriors Scrimshaw Knife” color scrimshaw by Gary Williams on ancient mammoth tusk ivory added to Boker knife. We replaced the original scales on this fine Boker knife with ancient mammoth tusk ivory. The ivory work was done by the late Ken Fredericks, a master craftsman. We only recently came upon the knife in a box in our storeroom, one of the very last of this kind of knife around as Boker no longer makes this model. Scrimshander Williams has chosen two stately Warriors depicted in astounding detail. You can discern the pattern in the blanket around the shoulder of one subject. Amazing work on a very rare knife.
