- Scissor Shears squeeze together for fast cutting of small diameter PE, PEX, thin wall PVC pipe, rubber or nylon tubing. Rotate scissor shears around tubing while squeezing handles together for the best cut. All models feature ribbed handles for more secure hold along with fiberglass strengthened nylon construction. Blade design maintains its sharp edge for long life and exact cuts. SC1 and SC125 industrial-grade blades are non-stick coated with a surface lubricant which lets blades slice smoothly through cut area.
