All About Pocket Knives

picked up a knife at a garage sale, it has no name that i can see and all it says on the one blade is a patent number,

PATENT 3,317,996

I did some minor searching and came across a possible lead of a colonial barlow style? any other clarity on model and type would greatly appreciated.


thanks,

Colonial hawkbill electrician's knife, probably made in the '70s.

Usually, the hawkbill blade was a secondary blade--I have one with three blades, and while the spear-point blade is marked, the hawkbill is not.
