The BMS tool looks nice, but it only lets you close the gap. You would still have to use another tool to open the gap. Like prongs on a wire gap tool, or a small pliers like the BMS video suggests. And backing the plug in and out of the BMS tool to open it would be tedious.
And even though I am huge tool snob/accumulator, I also find that the older I get, the less tolerance I have for spending money on expensive rarely used tools because "I'll have them the rest of my life".
