Made in the USA 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: The Standard Lansky Sharpening System features three knife sharpeners, each for a unique purpose: a red coarse ceramic hone (120 grit) for edge reconditioning, a green medium ceramic hone (280 grit) for sharpening and less frequent touch-ups, and a blue fine (600 grit) ceramic knife sharpener stone for frequent touch-ups to keep your blade paper-slicing sharp. 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 on the other side, 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 system is compatible with most knives, both fixed and folding. It's both a pocket knife and a chef knife sharpener in one.
