Just picked this one up, was advertised as an 8-4 bird and trout, but I had my suspicions about that, there was no picture of the back of the sheath to see the stamp. I took a chance and bought it, received it today and low and behold it's as I thought, a Stanaback special, of the 4" variety, That's about all I know about it, I guess even a blind squirrel finds a nut now and then.
