What good is an EDC knife if it isn't kept sharp? Even the best blades will gradually dull with consistent use - and added hand pressure and unnecessary hand movements can cause fingers to be where we don’t want them to be. With the SelecTool Master Sharpener, you can keep every blade in your life sharp and ready for safe and effective use. Also sharpens tools, mower blades, axes, hatchets, clippers, scissors, and anything with a cutting edge. Made in America.
