A number of years ago when I built building a Boarding Ladder Extension for the boat. I made it out of PVC and spare dock line. I purchased a Ridgid Plastic Pipe and Tubing Cutter to help cut the PVC material.
I recently found another use for it. That is cutting various type of hoses on board. From 1/2 inch water hose to aging propane hoses. The blade cut fast and cleanly, Making it a useful tool to have on board for projects or repairs.
