Tom Veff is well known as the preeminent professional knife sharpener in the Pacific Northwest, and also as the designer of our patented* Veffâ„¢ Serrations. He is truly "addicted to sharp," as are many other knife owners. But Tom was unhappy with the tapered diamond sharpeners that were available, so he designed the CRKT Veff Sharpâ„¢ to be the ultimate portable multipurpose field and bench sharpener. The system includes an anodized knurled aluminum handle and two threaded 600-grit diamond-coated sharpening rods. The smaller rod has three 2" straight sections in sizes 3/32", 3/16", and 1/4". The larger rod has three straight sections in sizes 11/32", 1/2" and 5/8". The larger rod also has a 6" flat side. The handle and rods fit neatly in a nylon storage pouch. The Veff Sharp is effective on most serrations and does not create egg-shaped serrations as tapered sharpeners do. It works equally well on gut hook knives and seat belt cutters. It is a versatile and indispensable tool that belongs in every workshop, tool box, tackle box and hunter's pack. It allows the user to keep a keen edge on all types of cutting tools including serrated and plain edge knives, wood chisels, wood carving and lathe tools, router bits, punches, scissors and saw chain.
