Best Wire Strippers for small AWG Electronic Repair in 2022?
bflores:
What is the purpose of all these round holes?

Tongue in cheek answer to the thread title: (you know it's the best when they have a blurry video with techno music, yeah this thing is like $1000)
More seriously I use the Knipex 12 12 02, I don't like the automatic strippers that clamp down on the wire. I think it's too expensive at full price but you can sometimes find them much cheaper on eBay from like a surplus store or second hand. It's a rebranded(?) Rennsteig so you can potentially score a deal.
Not sure about the top hole, maybe to gently bend the end of wire or something? Or it could be a really bad crimper? edit: or perhaps just a manufacturing thing
The bottom holes are for a length stop attachment like this.

Hey, at least it’s a Swiss manufacturer (Nitronic) using techno music by a Swiss-born artist (“Children” by Robert Miles). :P
In all fairness, those things really aren’t intended so much for ordinary wire as for small coax and wires with difficult insulation. At the workplace I start in August (where I did an internship last year) they have the robotic version of that, for working on tiny coax (like 2mm diameter Teflon-insulated micro coax).

Can you tell me more about it? I was considering getting one of those, until I realized it doesn’t have a die for the wire size I use the most (0.25mm2)! |O To cover the small wires I use most often, I’d have to buy the 12 12 02 and 12 12 06, with each one also covering numerous larger sizes I don’t care about. :(

They are one and the same. As best I can tell, Knipex (the pliers company) bought Rennsteig (the wire handling tool company) 30+ years ago, initially as an independent subsidiary, but more integrated over the years.

The actual stripping quality is A+, but the usability is more like a B rating.
Even though it has the "wire guides" you do have to take a bit of care to make sure the wire is mostly positioned in the cutting die. This is okay for bench use but sometimes in the field it can be annoying (like inside a car trying to repair wire and you have limited space to work with).
You also have to squeeze completely so the jaws open up and you can move the wire away. Sometimes when I'm tired I don't "cycle" the tool fully and the wire stays there and gets crushed by the tool closing back in, it basically destroys the wire so I have to cut and strip again (it has a very sudden "snap" back so it's too late to react in time hahaha).
Also the plastic length stop piece will disappear into the Shadow Realm, I lost mine a few months in. For anything critical I just trim down the exposed wire with a shear-type cable cutter (Knipex 95 11 165).
It's good for some extremely slippery PTFE wire that a cheaper Jokari style tool will just slip on (I think the better auto strippers might be okay, but I still don't like having the wire crushed because I often use crimp terminals that do the insulation crimp as well).
