Cone wrenches: I don't see a difference between Park, Shimano, or the store brand ones, they're all punched from sheet steel. Therefore I buy the cheapest possible. Rubber takes the edge off but still too sharp for high torque. Too short too!

BB & cassette sockets: work well but again, store brand are probably made the same so why not buy cheap? A bb tool permanently fixed to a breaker bar would be nice for really stuck bb's, but that's usually when ya put the tool in the vice and wrench the frame.

bottom line: nothing wrong with Park, but same quality is available in generics, and using better quality non-bike tools is best when possible.
