Considering how often side cutter go missing in a lab, the best one is the one you can find!
This is one of the few cases where I'd rather have 5 cheapies than one good one.
I agree, "ESD safe" is pretty much a crock, don't bother.
If they are fine enough to get in and cut SO IC legs I'm happy
Lindstrom are very nice.

Just wondering - does anyone here routinely wear a wriststrap ? I'd bet it's a small minority.

.and has anyone ever actually killed anything with static? I certanly haven't. PLenty of other ways, but not static.
The "ESD damage will cause failure down the road"argument always struck me as being a bit self-serving on the part of the semiconductor manufacturers.
I do use ESD straps etc, if they are provided in work situations just to be on the safe side.
Any advice about LINDSTROM 7191?, I'm thinking of buy one of those.
The rest of my entire toolkit was a classic victorinox swiss army knife, one flat head and two phillips screwdrivers, a box-knife, pair of scissors, my teeth (for stripping wire-wrap wire), and a cheap radio shack soldering iron that plugged into the wall, plus an analog VOM and a logic probe. Believe it or not, I built and debugged several fairly complex digital projects with that stuff. That is why I love my lab equipment so dearly today :-)

Cant' hurt except your wallet. The more you use a cutter, the more bang you get for an expensive tool in terms of easing repeating strain on your hand and losing the cutting edge of the tool. But if your use is just for a home lab or slightly more, its overkill, an $8 Xcelite with our without ESD protection will do for decades, until you lose it or it breaks from much use.
I also buy el cheapos to leave in toolkits. Just audition one from a supplier, and if it survives, buy enough from the same batch to stock your toolbox. If they get stolen or lost it won't hurt, I got Xcelite look alikes for $2 and bought 4; I got one to audition, cut up some wire, checked the edges of the cuts and the blades with a loupe, and all's well, got the rest. That's a catch as catch can on these cheapo tools, brand names are useless on them so you get them while you can.Any advice about LINDSTROM 7191?, I'm thinking of buy one of those.
Finally!
An answer to my question.
The money is a no problem in this case.
Thank you saturation.
One more thing--it is well known that small ESD discharges may not destroy a chip, but can cause it to function out of spec, or to prematurely fail remote from the event.
Maybe my european neighbors heard of a german company called Wiha?
I use that one presented in the link here.
Nice one, cuts just fine even larger wires up to 1mm, but the downside is the cost.

Is it well known? Often stated with a 'may' or 'can' but I have never seen any evidence offered and a device failure will never be proven to have been caused by an ESD event months or years ago.

If anyone has done any real study subjecting semiconductors to ESD discharges followed by life testing of apparent non-failures and controls I would like to see the results.
About Wiha .... I would love to get their free sample, if they do not afraid some real competition.
How about this one. Nothing special about that article--it was listed among hundreds others like it examining various processes and topologies.

If you are talking about MOSFET gate insulation for example it seems to me it either breaks down or it doesn't and if it doesn't break down there is no current flow and so no energy to cause any damage.
I suggest that probability is low to very low and so argument that you need to spend more money on ESD management because you could have an ESD problem without knowing it may, because it plays on fear of the unknown, be persuasive, but, actually doesn't hold much water.
The Knipex one is good, the Lindströms are better.

Don't confuse the cheaper Electronic Super Knips like the 78 03 125 ESD with the precision sidecutters like the 79 42 125 ESD
I buy the Xcelite cutters. They are cheap, reasonably well made, and seem to last as long as the more expensive varieties. They are also available at the local Home Depot branded as Crescent, but are identical otherwise.
