If you have no experience, please do not DISassemble the sword, because improper force will make the habaki deformation and gap. Copper is very soft, especially red copper. And remember don't close a sword too hard.

All of our tsuka of the swords facing to the international market are made sunken at the end, in order to prevent unevenness.

The hasaki under the yokotesuji was not entirely sharpened before. Because we make the real geometry yokotesuji. This case is normal amoun the mass-produced sword. It won't happen if it's not real geomitry yokotesuji. Now we have solved this problem. However with the increase in cost.

If I don't tell you that this is our works, can you figure out this is a Japanese sword made in China or a Japanese Nihonto?

Don't use Japanese sword as an axe like what we did. It is not correct, and would cause damage to sword. We do this just for a test.
