This includes three separate active cutting blades which are all able to be adjusted to the proper cutting depth via a Phillips screw setting for each blade.  Blades can be individually set to score the jacket so the inner conductors or shielding do not get damaged.  
 
The tool can be used for jacket stripping or scoring, including midspan access stripping, 2 step conductor preparation by having the .240” spaced side blades cut to different depths – one for jacket removal, the other for dielectric removal/conductor exposure.  The front blade can be used to slit a jacket end or complete a midspan cut. The Blue Adjustable Ringer™ handles cable diameters from .125”/3.2mm up to .250”/6.4mm.
