Then scrape some of that powder on the backside of you knife while letting some of the powder fall on to the leather strop, just enough to coat the leather. After coating it once the powder will last through several stropping so you don’t have to put it over every time.
Lay your knife flat on the leather and keep a downward pressure on the knife. Now draw the knife towards you while keeping the sharp edge trailing away from you. Your strop might turn black while the metal is being cut from the knife. After this, your knife is going to be razor sharp.
Though, you don’t necessarily have to use the stones if you want to strop again. Strop your knife even if it’s beginning to feel less sharp. Don’t wait until it becomes dull. Leather is also a good option and not just with wood carving knives, you can also sharpen whittling knives with leather.

Many carvers also prefer to sharpen at a hard angle of 24 to 29 degrees to have a better scooping control since the cutting edge rises with slight lowering of handle.

The blade’s point should also be needle sharp so that it can make precise incisions. The sides should also be properly polished in order to reduce friction as the knife cuts and carves the chips away. The edge is sharpened at a shallow angle and quite symmetrically.
First, you need to flatten and polish both faces. The blade’s edge needs to be straight as implied before. You can get this done by using sandpaper. Then you need to establish and hone the bevels. You can raise the blade at 8 to 10 degrees and raise the back of the blade. Hone the bevels that you formed on the coarse grits so that they burnish the surfaces as they cut. While carving, make sure to strop on a piece of leather. This will reduce the need of sharpening.
