Regularly stropping your knife blades and cutting knives will ensure you maintain the sharpest edge for the best performance of your investment. The strop is easy-to-use and helps align the micro-edge of any blade. The strop is 10-3/4" with a 5-1/2" x 1-5/8" leather strop on both sides. One side is the grain side (smooth) and the other side is the flesh side (rough). With the application of Jeweler s Rouge, the rough side will provide more abrasion than the smooth side.
