Your blade will now be very sharp, but with one last step, it will be deadly. Using a leather strop to finish the blade is no secret (cardboard works great, too), but the key is to add a little grit with any number of diamond sprays. These sprays have diamond particles suspended in the liquid. When sprayed on a leather strop, the particles help to smooth out the edge better than just leather. Be careful to keep the same angle that you built up with the diamond stone and make sure you don't roll the edge of the blade over on the leather. You'll find that with a little stropping, you will very quickly have a blade that is about as sharp as you can get.
