The MILWAUKEE compact knife sharpener features three sharpening surfaces compatible with most knives; a coarse carbide for quick edge setting, a fine ceramic to finish the sharpened edge and a diamond grit for freestyle specialty blade sharpening. It also offers a large finger loop for a secure grip and added control while sharpening. The compact size means it easy fits into pockets and tool belts or bags and has a magnet for easy, convenient storage on the jobsite.
