How do I tighten the fit on my saya?
Repeated sheathing and unsheathing of a katana, as in Iaido, will invariably cause the fit between the habaki and the saya to loosen. Our maintenance kits contain wooden shim stock that is specifically intended for use in maintaining the correct fit, whereby the katana will not fall from the saya under gravity. If the sword becomes loose in the saya, simply take a small piece of the shim (about 1″ long by 1/8″ wide) and superglue it into the mouth of the saya at the point where the back (mune) of the blade slides into the saya. If, at some point, the fit becomes very loose it may be necessary to glue a piece of shim (about 1″ square) into one side of the mouth of the saya, but this will rarely occur.
