Tom Veff is well known as the preeminent professional knife sharpener in the Pacific Northwest, and also as the designer of our patented Veff™ 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 Sharp™ to be the ultimate portable multipurpose field and bench sharpener.
