being a plane nut as a kid, all I see is Lightning and Mustang.
these type of openers have worked well when I have used them, but I have used the same can opener on the same simple Swiss Army knife I have owned for decades and it works just fine, although I too don't open a ton of cans.
the obvious handy thing about a multi knife or tool is that you won't ever lose or misplace a small can opener like these P ones. I still find my Sw army knife handy as it is my knive, cork opener etc, and I've always tied some orange rope on the lanyard to help keep track of it.
