Pedal wrenches and cone wrenches tend to be a little specialized and I haven't been lucky enough to find anything except bike specific tools that'll do that job.

The best bet would be to make a list of what you want to do on YOUR bike, find out EXACTLY what bike specific tool is needed to do the job, and then decide if generic stuff from the hardware store will do the job. Bikes don't all have the same components, and many of the tools included in most bike tool kids may never get used on YOUR bike. So the usual suggestion is to buy exactly what you need as you need it.

And another suggestion is to price the work that needs to be done (at LBS rates) vs the price of the tools. Some things aren't worth buying either.

If you decide to carry tools - a tool roll is convenient. They come in different sizes and colors - including pink if you look hard enough.
