Keep in mind that the blades and efficient design of these cutters also makes them dangerous, so always take the proper safety precautions while using them. They typically look like a pair of pliers, and are used by simply squeezing the handles together and letting the extra-sharp blade do the work for you. Regardless of the project, you’re going to need to cut that pipe to size, which is where these PVC pipe cutters come in. PVC pipe is useful for a range of tasks, from plumbing and irrigation applications, to framing material for hockey nets or other crafts.
