Besides most of my pocket knives have better can openers on them. So why carry another one. Other than as a status symbol of being in the club.
I use mine every 10-days or so to open a can, and it’s better then the one in my Swiss Champ knife. They both work, but the P-38 is faster to use and easier to use.
I don’t worry about “The Club” that you talk about, I have never ben one to run with the pack.
I have it because I find it useful.
