PVC pipe cutter blade, Precision ground cutting edge, Used for clean shearing cuts of PVC and polyethylene pipe. Cleanly cuts through hose, plastic tubing and PVC Schedule 40 pipe up to 2-1/2". Hardened steel blade design with pointed edge to pierce the pipe.
It was very easy to install, and comes already sharpened. However, there is no way to tell if the blade is hardened until I use it. Thus far it looks good.
