This professional manual 3-Stage sharpener applies a super sharp and durable edge on fishing and light hunting knives, pocket knives and serrated knives as well as both 15° and 20° edge household knives. Featuring a dedicated stage for fishing knives and another for hunting knives, and a separate ultrafine honing stage, the Chef'sChoice®Sportsman™ 4635 creates a razor sharp, double-beveled, arch-shaped edge that is stronger and lasts longer. Using Chef'sChoice signature 100% diamond abrasives in all three stages, it will sharpen faster than other abrasives and create shaving sharp edges. The Sportsman™ 4635 sharpens the entire length of the blade, from tip to bolster or handle. It's fast, safe and easy to use, requiring no guesswork. It can be used right or left handed and features an ergonomic handle that fits all hands. The slip resistant feet hold fast to the work surface. Safe for all quality knives. Engineered and assembled in the U.S.A.
