Use a fine-toothed saw cut PVC edge trim cleanly. If the teeth are as fine as possible it will give a better result. PVC edge trim typically refers to rigid plastic profiles like angle trims, flat strips, or plastic edging profiles. These are usually made from rigid PVC, which requires a precise and steady cutting method. Using a saw with fine teeth improves the end result, with cleaner cuts and reducing the risk of chipping.
It depends on if the edge trim is made from rigid or flexible material. If it is a soft flexible PVC, a sharp utility knife may suffice. .
For very thin profiles, a fine-toothed handsaw or hacksaw could be considered. Just ensure the trim is secured and cut slowly to avoid splintering. No matter the tool, always cut with controlled motion and support the material.
