You could cut your PVC pipes with a hacksaw or a chop saw, but the manufacturer says its Tailpiece Extension Cutter is a much better idea. It saves users time and material costs by making clean and straight cuts on polyethylene, polypropylene, and thin-walled PVC measuring 1 1/2 to 1 1/4 inches in diameter. A deburring feature eliminates the need for a second tool. Cost: $20.55. Ridgid. 800-769-7743.
