I think you guys are misinterpreting what the OP is looking for. I agree those small ring-type multi-size spoke wrenches with several different size slots around their edge are a poor excuse for spoke wrenches. But, I believe he is looking for a spoke wrench with a 3-sided nipple opening so it contacts 3 of the 4 sides of the nipple and has less chance of slipping and rounding it off. I think I've seen those but don't know who the maker is.
