Made in Russia, the TSPROF line of knife sharpeners can be described as game changing. These precision manufactured, and over-built sharpeners are the most robust guided sharpeners we’ve ever offered. Designed and built to last a couple generations, TSPROF sharpeners will consistently and accurately put a hair popping edge on your knives of all sizes. Although we do not consider these sharpeners to be best suited to the entry level buyer due to the price and precision adjustment, they are most definitely perfect for the customer who demands the best-built, best engineered guided system on the market. From impressive locking jaws to a very robust locking detent on the flipping mechanism, a TSPROF sharpener will undoubtedly exceed your expectations!
