Eze-Lap’s Knife Sharpening Kit Model DMD-KIT comes with three color-coded sharpening stones. The red-clad stone features 600 Fine grit, while the blue- and purple-clad stones feature Superfine 1,200 and Medium 400 grit abrasives. All sharpening surfaces feature Eze-Lap’s heat-treatment technique. The kit also includes a knife clamp with two angle-guides which “steer” the sharpening stones. The upper guide holds stones at a 20-degree angle while the lower guide uses a 25-degree angle. A roll pouch is also included.
