I have an old,old set of Kameapart type store irons that are made out of steel. I use the plastic ones to slide around taking a tire off and the steel ones for everything else. They have been bent many times and I just straighten them out. I keep breaking the plastic ones, but replace them for the above purpose. Everything at the local level is total junk now a days, except at the bike shops. Even then you should buy the professional grade. I have ruined my Park Tool pedal wrench, get the heavy duty professional one as we deal with old bikes that are rust welded beyond what a normal bike enthusiast deals with. Now a days its junk, kinda good OK stuff or really good stuff.
