Hi all, I recently purchased a stainless steel Kai Gunto. It is signed and has a Toyokawa inspection mark. It was suggested to me by the seller that the signature says "Matsunaga". I've tried to confirm this looking up Japanese Kanji marks online. I'm sure the second mark is "naga" 永, but I can't confirm the first mark is Matsu 松 . It just doesn't look right. Thought it could be Mitsu 光 but that doesn't look right either. Is it Matsunaga, or Mitsunaga or something else? Any ideas? Thanks.
