Greetings everyone,
I'm sure many of us deal with the problem of a bokken tsuba sliding down the blade and coming loose during practice? I can never seem to get that dome to do its job. I've been putting up with it my whole life but now I'm finally annoyed enough to look into it.
I haven't been able to find anything else on the topic on Google or YouTube or even here. So if anyone has any insight or ideas, I'd love to hear them.
Or should I take the general lack of content on a matter I assume is rather common place as evidence to there being no solution?
And before we recommend just training without the tsuba - I have tried that. My fingers get ever so chewed up.

A friend of mine replaced the rubber "habaki" with electrician's tape. Seemed to do the trick, at least for a while. Personally, I just push it back down now and then when it starts to move.

It's the steel on the inside that counts.

Better than electrical tape, use a piece of tanned leather and super-glue. Cut a strip of the leather long enough to wrap all the way around the blade, then glue the heck out of it. You may want to do this outdoors, because it will put off terrible fumes as the leather and super-glue go through a heating process. Once it is dry, put more glue on the outside. This is permanent. You only have one shot, so get it right the first time.

Not knowing the cause such as a crack or material I’d say shim it. Leather maybe too thick. Tape of various types (thicknesses) maybe a better answer. Rescue tape has no adhesive nor will it shrink with age such like electrical tape. But there are a host of tapes to choose from. Then there are papers. Maybe it won't by necessary to wrap all the way around, and place whatever on one or two sides. It all depends on the thickness of the material and the size of the gap. CA glue will hold everything together if need be, or possibly just a force fit will do. As for my bokken, it has no tsuba.

I wrapped it up with medical tape and put the dome back on. It seems to be holding pretty good. I'll test it with practice as soon as I can and let you know how it goes.

I just JB Weld the tsuba in place (blade side of tsuba), and use the rubber retainer to cover it. Will never move again.

Yes I have had similar problems with bokken training swords. If the sword has a rubber or plastic habaki, I use electrical tape on the end of the habaki. Three or four wraps is more than enough. Works very good and you can always remove the tape if you need to replace the Tsuba. If you glue it in place then you may not be able to remove it if you need to later on.

Double wrap the rubber habaki w a broccoli elastic (if a small elastic use only one wrap...why am I explaining how to use elastic?).
Seems to do the job for me.
Btw, practice without a tsuba will help you improve your grip awareness if using for iai. Ouro
