not good with 24 awg stranded wire
Customer Rating: 




bottom line: this irwin self-adjusting wire stripper did not work well with the 24 awg stranded wire i tried it on. however, it worked beautifully with 22 awg solid core wire.
this irwin stripper works by gripping the wire with two clamps, the left one for holding the wire and the right one for stripping it with a sharp edge. as you close your grip on the handles, both clamps lock down on the wire. when you completely close your grip on the handles, the two locked down clamps then come apart, stripping the wire. at least in theory.
the problem i had with the irwin stripper is that the clamps did not provide enough force to hold down a thin 24 awg stranded wire. as a result, the insulation becomes partially pierced by the stripper and stretched a bit without being completely removed. if you manually press down on the left clamp before completely closing your grip to strip the wire, then the insulation will come off, but you also make a dent in the wire, exposing a little part of the wire away from the tip.
there is a swivel knob to micro-adjust the irwin stripper for thin wire gauges. however, even with the micro adjuster at its tightest, the clamps are still too loose to really work with 24 awg.
i also tried this irwin stripper with 22 awg solid core wire, which worked exactly as it should. just beautiful. i really really wanted to like this product, but i bought this stripper to work with the thinnest wire gauge it is spec'd to handle and things just didn't work out. it's not a bad product for thicker wires though. irwin should advertise these wire strippers for 10-22 awg rather than 10-24 awg.
Throw all of your other wire strippers away!!!

Like other reviewers, I've tried everything out there (including my teeth) to strip wire... I've done my share of knuckle banging, finger cutting, and everything else you can imagine trying to strip wire for electrical outlets, recessed lighting, ceiling speakers, etc... I decided to give these a try (why not, I've used everything else and if they didn't work, I'd toss them just like many tools before it)... what a pleasant suprise... They work great and take just seconds to use... I get a clean strip 95% of the time (the other 5%, I have to run the wire stripper on the wire twice cause the first attempt didn't fully remove the insulation and only happens sometimes on heavy gauge wire)... No more using wire cutters (trying to delicately twist side to side on the insulation without actually cutting the wire), manual wire strippers, utility knives, and even my teeth... I'd pay double for these if I had too... I just wish I had found these years earlier~~~~
