Prevent electrical breakdown from the cable core to the sheath when installing a pressure testing fitting by using this handy tool to separate the core and sheath with strips of muslin.

It's similar to a small screwdriver, but with a special hook-shaped tow at the end of the blade you can use to smooth the sheath underside and tuck muslin underneath.
