EdgeLogix Ceramic Pocket Sharpener - Red (CP021R) packs a lot of sharp-making into a very small size. Using ceramic for both the coarse and the fine stages, this sharpener isn?t nearly as aggressive as a comparable carbide sharpener, which can tear steel off the edge of your knife if you?re not careful. However, this sharpener will hone and sharpen extremely well, bringing an edge back to shaving sharpness in a matter of seconds without running the risk of shaving too much off. Whether you?re on the boat, up a mountain, or in the back country, you?ll be happy to have this sharpener to give your blade a few quick licks.
