The surface is made of top-grain cowhide tanned leather, one side is smooth, and the other is hairy. Both sides can be used. Now apply a little oil to the leather, then apply the sharpening paste on it. First use the coarse hairy side to sharpen the blade, and then use the smooth fine side to make the blade even sharper.
Maintenance: When the blade is not smooth and sharp, it is usually polished with a sharpening stone or sharpening paste to extend the lifespan of the knife. Generally, oil stones are not used to sharpen the blade, unless it is necessary to sharpen the angle of the blade. Those who are not familiar with sharpening can consider purchasing a leather carving knife angle adjustment tool's mokada frame to maintain the blade from being worn out.
1. Apply a small amount of oil to the sharpening stone, and first apply the sharpening paste to the leather surface of the sharpening board.
2. During use, the oil is easily volatilized, so if it dries, add some oil to maintain the lubrication state and sharpen the knife.
3. Before carving, rub the knife back and forth on the sharpening paste on the grinding board a few times. Drag and spin the knife blade on the leather sharpening board in the direction of your hand, do not push towards the blade direction.
4. Then, perform the same operation on the leather smooth surface of the grinding board. The smooth surface can be ground more finely, which will make the carved lines smoother and more fluid after the knife is polished. After the grinding is complete, start carving with the rotary carving knife.
