Your best friend here is the reciprocating saw—specifically, one with a short blade. Think of it like a tiny, angry beaver that can gnaw through metal without needing a full swing. If you can’t fit a standard saw, try a mini hacksaw or a compact angle grinder with a thin cutoff wheel. These are like the Swiss Army knives of tight spaces.
But wait—there’s a quieter, cooler option: the pipe cutter with a ratcheting mechanism. It wraps around the pipe like a gentle but firm snake. You just twist and squeeze, and it scores the metal cleanly, even if your elbow is jammed against a wall. It’s almost meditative, right? No sparks, no noise, just a calm crunch.
