Was going to post on identifying but I figured it out myself
Mine appears to be older than the ones I've looked at so far but it may just be from abuse- how long have they been making them, and is there a way to find out age and such?
Can't figure out how to post pics sorry
Blade markings are as follows-
Right side SCHRADE-WALDEN
N.Y - U.S.A.
Left side. 150T pat pend.
5333(B or 8)
Thanks!
