All About Pocket Knives

Interested in info on this knife I got for my husband for $15 at a flea market. Is it old? The handle material is nice I think. Thanks for any help. I did get info on the company but haven’t been able to find a knife exactly like this. ]

Since it has BOULDER, COLO. in the stamp, it was made no later than 1972, as that line was dropped starting in 1973.

The pattern is a 48A bird & trout. The specific model is 648A. Age is dependent on where the model stamp is located.

You didn't include a pic of the pile side or the guard face. Is there a 648A stamped in either place?

Thanks so much. I never would have looked there. Yes there is a 648.
