The Work Sharp Benchtop Angle Set Knife Sharpener is a complete, versatile and adjustable knife sharpener. The 3 sided sharpening rods provide coarse and fine grit diamond plates to quickly restore a sharp edge, while the fine grit ceramic stone creates an incredibly keen edge on any knife. Rods rotate for quick indexing between grits making it fast and easy. Sharpening Angles can be set to 15°, 17.5°, 20°, 22.5° or 25°. Conveniently folds down and stows in a compact case. The Angle Set Tri-Brasive Rods were designed to rotate 360 degrees so you aren’t locked in (pun intended) to a single position of approach for sharpening. It allows for moving quickly between abrasive surfaces and creating perfectly comfortable ergonomics when sharpening. Adjust one side in a little, and the other out – make it most comfortable for you knowing it won’t affect the sharpening angle selected. Designed with knife making legend Ken Onion, this sharpener is a must have for any edge enthusiast.
