For the handle, take 2 pieces of wood. When finished, the 2 pieces of wood should lay together perfectly with the tang inserted between them. When you are satisfied they fit well, slightly roughen the inside wood and then spread a good epoxy resin glue all over. Put the tang in place, press the 2 wooden handle halves together and clamp. Leave clamped for at least 3 days.
Some traditions call for certain signs to be carved on the handle.
Even if your does not, you may wish to add some decoration. I would certainly recommend at least putting your Craft Name or monogram on it. You might also like to etch something on the blade, this isn't difficult to do.
