The PipeKnife sealant cutout tools were invented by autoglass technicians to cut the urethane used to seal the windshield to the frame of the car.
The design was specifically created to reach between the dash and windshield and provide extra reach and power to make the cut. The long-handled utility knife design also has room for extra blade storage in the barrel end of the knife.
The PipeKnife was the original cutout tool, or long knife, commercialized for the AGR industry. It was invented and patented in 1987 and has proven to be the most popular sealant cutout tool in the autoglass replacement industry.
The Original PipeKnife is 14” in length and the 18” long PipeKnife-XL is the most recent addition to the popular PipeKnife product line. Both PipeKnife tools use standard 2-notch utility blades or will also hold the special serrated PipeKnife blade (listed in accessories) or other long-length utility blades.
