Coburn's HD Tube Cutter is all metal and comes with an arrowhead-style blade. The blade punctures, holds, and cuts the tubing in one easy motion. The spring-loaded handle makes repeated cuts easy. The jaw design cradles the material and has a maximum cutting opening of 1-7/16". The blade rests inside the closed jaw for safety. The cutter works well on a variety of materials, including rubber, silicone, and PVC.
