Filzer FTL. (well, not really.. my own mistake), hooray for MEC's return policy!
Hozan also makes the 2 sided model with the smaller end. I still use the bigger end for lockrings but only those without opposing notches. This one is about $20 cheaper than the pliers..$35...and is substantially better than any other single notch tool I have used.
