Seatek RF170 1-1/2" roto split
The RF-170 is an amazing accomplishment in the design of a compact hand tool!   Cables as large as 1-1/2 trade size flex can be cut with ease using the  patented three position cutting system.  A few turns of the crank of this compact tool produces a clean slit through armored casing.  Push the top forward to make another cut to completely cut through the convolution.  Takes only a few seconds, simply untwist to strip!  Safe & does not damage wires due to the unique built-in depth of cut stop. (Adjustment screw provided for thin walled cables.)  The Roto-Flex also spells the end to nicked fingers and cut knees.  The open channel construction pioneered by Seatek allows cutting in the middle of a roll.  Simplicity at its best!
