John Gibson comments on his site about this model:
"Seven Inch Recon made by Japan Sword and so marked on the ricasso. It has a blue blade and comes with the original scabbard. Only a couple of these are know to exist."
The knife blade measures 7".  This knife measures 11 3/4" overall.  The blade is blued.  The ricasso is stamped 'JAPAN   SWORD'.
The sheath, of course, is original to the knife.
