I think that is one big advantage of expensive tools like Snap-On and Mac; they use better steel and thus can make thinner wrenches.

I started grinding on a sacrificial 17mm wrench and got it to look right by eye, but I also grabbed my vice grips beofore I wrestled my way under the car. I ditched my creeper because it puts my nose about 1" from the floor of the car. Anyway once in position I realized I did not grind enough off the wrench so I gave the vice grips a try and it worked.
