Step your tool game up at least a half an inch with the Craftsman MACH Series 8-IN Adjustable Slide Wrench.
Not only is this wrench going to stunt when you whip it out to fix your friend's bike but it possesses some amazing advances compared to the crescent wrench currently in your toolbox. A slide-adjustment makes it easy to adjust on the fly. A ratcheting feature that combines tightening and loosening. Flat black finish and a lifetime warranty.
