Hello, I purchased a Wakizashi with a koshirae several years ago. Apparently, it wasn’t made for my sword. It’s slightly loose and a bit too long. I’ve attached a photo. I assume it’s from the Edo period. The looseness isn’t a problem for me, but I’d like to shorten the saya by 6 cm. In my opinion, the kojiri could also be moved easily because the difference in diameter at the point where it would be cut is about 3.5 mm larger than the diameter at the end of the saya where the kojiri is currently mounted. Do you think it makes sense to do this? I don’t want to damage the antique in any way. Do you have any idea what kind of adhesive should be used, and is there a specialist in Europe who could do this, or would a good local carpenter be able to handle it? Thanks in advance to everyone!
