I'm not really sure the origins of this knife.  It is old and I inherited it.  It says "Sakai King Knife" on the box.  It appears to be a Nakiri knife, but that's just my guess.  It has "225" written on it, not sure what that means.  The blade is a little over 6" long.  It also has "Japan Fukui" printed on the blade.  If more pictures are desired, please let me know.
