I didn't know until this thread the RIGID made these. THAT might be worth buying but those "store" tube cutters suck!
The local hardware store uses one off their racks to cut tubing and it gets replaced about once a month. Of course that's business use, a lot more abuse over time than one of us would put them through, but I wouldn't want to
ever buy another if I bought a special tool like that and doubt the "store" brands wouldn't last. I'd rather buy the small pruners and trim the bushes too ...
