A PVC cutter makes a clean, square, burr-free cut that seats fully into a fitting - the kind of cut a hacksaw rarely gives. Ratchet cutters multiply hand force to shear pipe in stages, while scissor-style cutters are quick on thinner wall and tubing.
Size the cutter to your pipe outside diameter: our KwikCut and ratchet cutters handle up to about 1-5/8 in. OD, covering typical 1 in. and 1-1/4 in. irrigation PVC. Keep a spare replacement blade on hand, since a sharp blade is what keeps cuts clean.
