I don't normally post over here.
A few years back CS made a Puuko. I can't remember the name of it.
Thanks in advance.

There's the Finn Bear, which is the cheap version, and then there was the Sisu, which had a San Mai blade.

I think it was expensive, more like a collector's item than a user. It had limited appeal.
