Hi bdev.
I hope that I can help.
I believe that the character is the maker's name.
If I am not mistaken it should read "Seki Yoshimitsu"
Last name Seki 関
First name Yoshimitsu　義光
I tried to find some information about it in Japanese but couldn't find much info.
I only managed to find a blog by an individual that bought one at an antique shop in Japan.
Apparently he tried to look for some info as well but could not find out much about the knife.
