^^ I thought unagi was what you cut with it?
I usually write the shorter version of the names (in this case unagisaki) because I am lazy, at least I'm sure I've hear them called that (if I'm wrong then I'm stupid too). Sort of how I'll use yanagi instead of yanagiba
I would just sharpen it like an usuba only you have to do it in both sections.
I always wondered why the handle was shaped like that..
