The Knife & Tool Sharpener is an improvement upon the original Work Sharp Knife & Tool Sharpener which was the first knife sharpener designed to sharpen every knife you own. Building on that success the new Mk.2 provides even more sharpening benefit for the avid knife user. Using 1/2” x 12” flexible abrasive belts in coarse, medium and fine grits (P80, P220, 6000) the sharpener is able to sharpen not just straight bladed knives, but also curved knives, tanto blades, filet knives, serrated knives, gut hooks and virtually any other shape of knife blade.
