PopCut instant Co2 power copper tube cutter
I did this one for an air conditioner repair friend a few years ago. The patentable part (but NOT patented) was designing the cutter blade (which fires like a bullet) to cut debrie free through all pipe sizes from 3/4" to 1/4". Everything else can be found inside a Co2 pistol or rifle. This makes copper plumbing and HVAC replacements a breeze!
