Tricks for loosening too tight hex bolts?

[farrellcollie]

I am using a hex key - (I think - a 5-6 inch piece of metal that has about an 11/2 inch bendy part so that it looks like a tall L). I agree about the hammer - it would just be satisfying until I wrecked something. The reason I think I am right aobut the turning is that I read about it on the park tools site and I am turning in the opposite direction of what I did to get the first one off. I don't think it is rusty - just overtightened - it is my dahon folding bike - and just about every bolt has been over tightened. so much so that there are complaints about it on their website. I may just have to take it bike shop tomorrow. It is not really a problem except that I hate to take them things that I can do myself - like changing pedal (unless one won't come off) Thanks
