Wire Strippers

Irwin Vise Grip strippers, the best semipro strippers - fail miserably at 14/2 romex and larger. At best mixed results. See

Review of Knipex NexStrip, very expensive stripper-cutter-crimper with wide range of wire size.

12-72-190 - [1]

Does the Knipex standard work as well? 12-62-80 - not adjustable:

Seems to work.

12 42 195 -l [2]. Has replaceable blades.

12 52 195 - PreciStrip [3]. Precision adjustable. Mfg website - [4]. But - DOES NOT WORK FOR ROMEX (THHN, harder wire insulation) - only for Eurosoft. Search for review with Romex. [5]. They explicitly recommend 12-62-80 - the non-adjustable version.

12-64-180 - for exterior of Romex [6]. This review states that the expensive multi NexStrip starts to fail above ga 10 for heavy insulation wires.

Klein [7] is also mentioned here [8]. The Klein review says these work great on the jacket - and decent on individual wires. We want individual wire perfection.
