Wire Strippers
Irwin Vise Grip strippers, the best semipro strippers - fail miserably at 14/2 romex and larger. At best mixed results. See [1].
Review of Knipex NexStrip, very expensive stripper-cutter-crimper with wide range of wire size.
12-72-190 - [2]
Does the Knipex standard work as well? 12-62-80 - not adjustable:
Seems to work.
12 42 195 -l [3]. Has replaceable blades.
12 52 195 - PreciStrip [4]. Precision adjustable. Mfg website - [5]. But - DOES NOT WORK FOR ROMEX (THHN, harder wire insulation) - only for Eurosoft. Search for review with Romex. [6]. They explicitly recommend 12-62-80 - the non-adjustable version.
12-64-180 - for exterior of Romex [7]. This review states that the expensive multi NexStrip starts to fail above ga 10 for heavy insulation wires.
Klein [8] is also mentioned here [9]. The Klein review says these work great on the jacket - and decent on individual wires. We want individual wire perfection.
