A great non-slip adjustable wrench from Irwin. If you are doing any plumbing at home then this needs to be in your toolbag. The thing about most adjustable wrenches is that they "adjust" themselves halfway through tightening a nut. This immediately leads to broken nuckles and a lot of bad language! You can take the stress out of nuts and bolts with this adjustable wrench from Irwin....It just makes sense.
