How to sharpen a razor.

With a light hand, let the blade make a five-degree angle. On the sharpening stone evenly hit the river clay in a clockwise direction, three times before and once after. Sharpen with an edge three times the reverse side once. The arm must be flat. If you feel the knife body on the sharpening stone resistance means that the strength is not even do not push. It is also best to soak the knife in hot water for a while before sharpening. Putting some salt is the best. Sharpen fast. It took three years of learning from the master to pass. I hope it will help you.
