I have plentiful supply of quality tools. However - not 'bike specialty tools - like cone wrenches. I'm pretty utilitarian about a lot of things - but not tools. Where is a good source for tools? What are some other common specialty tools? I know there is splined looking socket for working on the cassette. How many variations of those are there? I'm not going into business - just trying to keep my own junk going, learn and build a few 'things'.
As you perform your own maintenance/building, the tools you need will become evident. There are so many different specialty tools, it would be difficult to name them all. As far as cassette tools, you will probably only ever need one kind, unless you encounter freewheels.
