I "inherited" this blade and it is part of my collection which I am selling off piece by piece.
I don't have an idea how old this is but it has been in my collection for around 25 years, I suspect it is 30 to 35 years old, I have no way of knowing.
Made in Japan. Has a rubber grip and brass guard and pommel, original sheath.
8" overall length with a 3 5/8"edge, the ricasso is 1/2".
$100.00 gets it to your door in AZ.
