A few years ago I found a paneer pack on the side of a bike path and it contained a few odds and ends including a Brooks seat wrench, a chain splitter with a replaceable master link, chain lube,a spare tube, and a Multi tool that was well worn on the handle. I was surprised to see how many tools fit in this thing that is only slightly larger than a folding hex key set. I posted on the local CL lost and found and asked around those that frequent the bike path and I ended up keeping the pack and its contents. The Multi tool looks like it says Advent or something on the side and I carry it instead of my old Swiss Army knife . I am happy to say I have never used it except to help someone with a loose stem bolt. I have seen several variations of these things and the one that really impressed me was the Topeak Alien set, it seemed to have just about everything.
