Identifying a wooden katana

[shankbone]

I have this small, hardwood katana. It measures to about 55 centimeters or 22 inches from the tip to the bottom of the handle.

I don't know a lot about classifactions of swords, but I believe this is about the same length as a wakizashi samurai sword. So do I call this a wooden wakizashi or something else? It doesn't matter all that much but I'd just like the correct name.

I think that still would qualify as a bokken. Maybe this will help:

It's a bokken/bokuto. Kodachi (wakizashi) by its length.
