Kodachi with saya

Dear Budo friends,
here is first kodachi  with saya, but not ordinary saya, this saya have KAERITSUNO (small hook). 

 Due to constant improvement, here's another novelty from my little workshop.

If you look at the professional  literature about Nihonto you will find out that Kaeritsuno most commonly appear on Kodachi and Tanto koshirae.
