This wrench was unusable at the time of delivery. The set screw that holds the pivot pin in place is too long causing it to hit the body of the angle grinder and preventing the pins from adjusting properly. Once I sawed the screw to the right length, it worked fine, although it was a little fiddly to get the two pins the right distance apart. what it is for and how it is used. A quick look through the related items section of the Revain page revealed another similar wrench with the correct set screw length, good reviews and a lower price. Take this, not that.
