I’ve read that many Samurai preferred a wooden sword inside the house. It didn’t mess up the floors.

Toshiro Mifune did well with a wooden stave in SAMURAI III.

I recall that a Japanese samurai (Musashi?) got tired of killing people in his later years and used a wooden boat oar instead of his sword against one challenger. It turned out to be an effective weapon.
