Secure Knife Clamp: A multi-angle clamp is included to hold the blade securely, making this Lansky knife sharpener kit simple to use. Keeping a consistent angle with this knife sharpener tool is much easier than with a knife sharpening stone. Complete Pocket Knife Sharpening Kit: This diamond knife sharpening kit features four knife sharpeners, each for a unique purpose: a silver extra-coarse hone (70 grit diamond), a purple coarse hone (120 grit diamond) for edge reconditioning, an orange medium hone (280 grit diamond) for sharpening and less frequent touch-ups, and a gold fine hone (600 grit diamond) for frequent touch-ups to keep your blade paper-slicing sharp. It also includes a brush for cleaning. Precision Knife Sharpener: The components in this Lansky knife sharpening system allow you to fix an angle of your choice for your edge, ensuring a consistent, clean bevel. For best results, attach the clamp to one of Lansky's table mounts like the Super C Clamp or the Universal Mount. Straightforward Operation: Using this knife sharpener tool is simple: First, attach the brackets to a sturdy surface and tighten the clamp on your knife's blade. Select the sharpening stone you'd like to use and attach it to a rod. Insert the rod into one of the angle slots in the bracket and begin working the stone along your knife's bevel. Repeat, going back and forth between the sides as you work through progressively finer grits. Before you know it, you'll have a razor-sharp edge! Versatile Application: This diamond sharpening stone set is compatible with most knives, both fixed and folding. It's both a pocket knife and a chef knife sharpener in one.
