The first step needed to maintain an edge on your woodcarving knife is to test the knife each time before use. One sign of a woodcarving knife becoming dull is for the cuts to come off in small splinters instead of curled shavings. One of the easiest ways to sharpen your knife is to hold it at a 20 degree angle on your sharping belt and push away from your person. You must repeat the rolling motion shown in the video around ten to twelve times before retesting for sharpness. This step can be repeated until the desired blade angle has been reached.
