To sharpen knives at home, you will need a sharpening stone, damp tea towel, water, steel, and paper with a 90 degree corner. You prepare by placing the damp towel and stone on the bench, then use folded paper to guide the knife to a 22 degree angle on the stone. The method is to sweep the knife held at a locked wrist from heel to point 10 times on each side of the coarse and fine stones, then finish on steel a few times per side to maintain the angle.
