The real villain here isn’t the copper. It’s the three inches of air between the pipe and the drywall. That gap is the equivalent of trying to fit a giraffe into a Smart Car—technically doable, but nobody will respect you for trying.
Inside that tiny void, you can’t use a normal hacksaw. You can’t use your elbow, you can’t use your feelings, and you definitely can’t use a power tool without accidentally cutting your own thumb off. Surprising fact number one: copper pipes are surprisingly soft, but your skin is softer… and it bleeds in a really inconvenient shade of red.
The Secret Weapon: The Mini Tubing Cutter
Your knight in shining armor is the mini tubing cutter. Yes, it looks like a toy you’d find in a kid’s chemistry set, but it is a savage beast. This little wheel of justice can fit into gaps as small as one inch—which is just enough room to make you feel competent.
You simply clamp it around the pipe, twist the knob, and spin. It’s like a tiny, vengeful hamster running in a wheel, but instead of cuteness, you get a clean cut. And if you think that’s easy, try doing it upside down, with a flashlight held in your teeth, while your other arm pins the pipe in place. Surprising fact number two: the average DIY plumber burns 47 calories per minute cursing in confined spaces. I made that up, but it feels true.
