The Master Blaster is a two part comb pick attack that will open Master #3 and as a bonus the same tool will also easily open the smaller Master #1. This tool bypasses and opens the MOST POPULAR pad lock in north America with little effort or training. The trick to making it work is using a shim tool to lift the pins out of the way so the comb pick can be set in place. The Master Blaster should be a part of every LEO/FIRE/MIL every day carry.  When training with the MASTER BLASTER using a tension wrench to test and turn the core advisable.  Shim is cut from .015 stainless Comb is cut from .032 stainless   As seen in Recoil magazine!
