Comments: This classic five-blade Sow Belly by Slip-joint Master Bill Ruple is another winner. Brand new from the January 2020 Las Vegas Knife Show. It has beautifully ground and razor sharp blades which make it a perfect daily carry knife. And there is a classic Ball Sack stainless escutcheon topping off the gloriously colored Presentation Grade Fossil Mammoth scales. With superb fit and finish we have another multi-blade masterpiece from the Ruple workshop.
