This is a repair that is often done when a Kanna has a split or check in the wood. Rather than simply filling it with epoxy and/or superglue, it is way better to use a mechanical connection to repair the crack and ensure that it doesn’t expand or get worse in the following years.

The key for these (literally) is to make the spline as strong as possible, and to ensure that it stays put, it does need to be glued in place.

The maker of this dai is a gentleman named Joshua Villegas. The dai is exceptional and the crack was not the result of any lack of craftsmanship on his part, it was solely the result of the wood stresses being released and the wood expanding and contracting with the cold air going on around it.

Alot of times craftsman will spline kanna at the wear points in order to keep the dai as flat and straight as possible as it moves and twists over the years. In this case I didn’t have that option as the crack was in a place that never makes contact with the work.

Anyways, just a short little repair. Thanks for reading/watching!
