Review on TOFL Deburring Copper Cleaner Plastic by Daniel Aboubakar

Tried this new reamer/chamfer on 1/2" and 3/4" tubing; as indicated in the title. Worked well on all 3 pipe types; inner and outer edges. It took some effort to work the tool on the pipe; it's not the same as cutting butter. My main performance was endurance; How long do the blades stay sharp? I tried ends cut with a hacksaw and pipe cutter. Worked best on the ends of the pipe cutter.
