P-51
This is the big brother of the classic P-38 can opener. Labeled “US SHELBY CO” on the back, it’s just a cool little item I threw in. This can opener is only 2 x 0.75 inches. I have keys that are bigger. Haven’t opened any cans yet, but will soon. My only concern is the tip. Not an issue when laying flat, but even closed the blade can lift up from surface. I can see stabbing myself pulling keys from my pocket.
I have 2 P-51's from Countycomm also. I have put a piece of heatshrink around the "blade" and shurnk it. The heatshrink has the advantage of no sticky residue left behind like electrical tape.
