When I was a rookie motorcyclist going through cans of oil, this was the thing to have. Those oil cans were maybe 30 gauge steel? When they started making the sides out of cardboard, it was easy to cut the cardboard with a screwdriver.
But, before the days of pop top cans or twist offs, the pointy end was used to open oil cans and the other end was used to open beer bottles.
Now oil comes in a bottle, bottles have Twist Offs, and my knife normally stays in my saddlebag, except occasionally to open snack foods.
I still haven't polished up the buck knife. Now I feel like a slacker.
Especially considering I have a big electric buffer and seven kinds of Polish.
But I've been busy reloading ammunition and preparing for a big range trip this Friday.
Also I bought a steel locker for my ammunition and powder and and I've been filling that up and rearranging my gun safe which now has lots more room.
When I rounded up all my spare lead & put it in one spot, I calculated that I have nearly 300 pounds.
