Signature help please, Japanese hand forged dagger

Can somebody identify the type of knife this is, also, what it says. It is very, very sharp, scalpel edge.

 

It looks like it's called a folding kiridashi knife. Used for everything from gardening to wood carving. The maker's mark might not be too hard to find now that you have keywords.

 

The marks on these two knives look like they match yours, so I think the brand name is Mikihisa.
