This thread got me thinking (a dangerous thing at times) and I replaced the Vic Pioneer (silver alox) that was in my Mission Wallet with a Vic Spartan (red plastic). I do believe that will be my go-to knife in public -- it's just a Swiss Army Knife.

In the process I got a small blade, tweezers, toothpick and corkscrew; I saved all of 10 grams. I don't get the strength of the aluminum sides, but in that knife it isn't critical. The Pioneer goes to the bullpen while I think about where it would be most useful to be stashed.
