This custom one-of-a-kind knife, The Doctor Knife, was crafted by Bill Ruple. Since 1988, Bill has historically built and sold custom knives, with his specialty being multi-blade folding knives. His traditional knives come equipped with anywhere from one to five blades. Each stainless steel knife’s profile is made crisply through the stock removal method. As always Bill has added his signature engraving on the largest blade.
