This is a quick and handy tool to have with you at all times! Features exclusive comfort grip rubber over-mold design, so it's easy to use and very intuitive. One side features tungsten carbide for sharpening and the other side features crock sticks to polish. Just 3-4 strokes in each slot and your knife is sharp! Color will vary.
I got this for my birthday and it has helped keep my knives sharp and usable.
