70’s Lone Star Church Key/Bottle Opener Keychain
Puncture a can or pop a bottle all from the comfort of your keyring. You will also find other uses with time. Pearl made a lot of these, Lone Star made less. This is the only one I’ve ever had. Just enough patina to prove it was a part of the action back in them good old days. Conservative estimate is 70’s but 60’s is also likely.
