I've got a terrible habit of riding off without remembering to put a saddle bag on the bike I'm using, so I've been planning to get a dedicated saddle bag for each bike. This tool seems like a great option for populating the bags for the bikes I ride less often. I've got a couple of pricey Crank Brothers multi-tools that I hardly ever actually use but carry with me whenever I don't forget. I can't see buying one of those for each bike.
