Once the cut is through, you’ll feel a surge of victory. But don’t celebrate too loudly—you’ll knock over the toolbox. Now you have to deburr the inside of the pipe, because that sharp edge will ruin your fitting and cause a leak down the road.
Use a deburring tool or a round file. If you don’t have either, a rolled-up piece of sandpaper works in a pinch. It’s the plumbing equivalent of using a shoe as a hammer—unsightly, but it gets the job done.
And you gotta clean the outside edge too, or your solder joint will look like a melted marshmallow. A little steel wool works wonders, just like it does for your rusty garden shears.

Real Talk: When to Give Up
Sometimes, the space is just too tight. You’re sweating, your hand is cramping, and the pipe is in a spot that even a raccoon couldn’t reach. That’s when you admit: maybe this isn’t a DIY job.
Calling a plumber isn’t failure—it’s wisdom. I once spent three hours trying to cut a pipe behind a toilet, only to have a pro do it in ten minutes with a tool I didn’t know existed. He called it a “mini ratchet cutter.” I called it magic.
And hey, if you do manage to cut it yourself, you get bragging rights. You can tell your friends, “I cut copper in a space smaller than a breadbox,” and they’ll nod like they understand, but they really don’t. Only you and your aching back know the truth.
