If you enjoy using a sharp knife, we highly recommend learning how to sharpen and maintain your edge on a Japanese Whetstone. They come in different grit levels, like sandpaper. The lower the number, the coarser the stone and the more material it removes. The higher the number, the finer the stone and the more it will polish and refine your edge.
