Actually the Allen brand is a nice brand of hex wrenches. I don't buy hex wrenches made for bikes, I got a set because I needed them for car stuff and of course they work on bikes, no need to go buy special hex tools (or some other tools) just because your working on a bike. Usually when I work on my bikes I can handle all the minor stuff with the Park MTB3 mini tool I keep in the seat bag, so use it more then my other tools because it's already with the bike and I don't have run to my tool box. The Park MTB3 mini is holding up just fine for the last 12 or 15 years I've had it and I've used it a lot. I even fixed a person's car with it once.
