Designed with your safety in mind, this all metal tool is capable of stripping wire from  3/8"  to 2".    There is a finger pull mounted on the end of the tool to help the operator  pull while stripping the wire in a  longitudinal direction.  The blade is adjustable from the rear of the tool with a simple turn of the knob and can be adjusted up to 1/4" in depth.  Strip the wire circumference and then rotate the tool 90 degrees and pull the tool in a longitudinal direction removing the remaining sheathing.   Comes with a spare blade in the handle.
