Review on Ampco Safety Tools W 71 Non Sparking by Jeremy Hudson

My trusty hazardous area wrench broke after a year of commercial use. The jaw broke when tightening the brass tubes. I still have one in my kit that I used as a spare until the replacement came. Anyway, as far as the actual rating goes. I use these keys in a lab where there is always saline and high humidity. I like these aluminum bronze wrenches because they cost a lot less than the titanium ones. When my wrench broke it just lost its original shine.
