Thanks for the photo, Poppy. I went back to a photo of the one that I saw in a local store and I see that it also has that offset cam. I didn't notice that before.
Interesting, but it's not just about those newer models with 'offset cam'. I might have to try one of those some time, but it's their other 'standard' models (along with their various side cutters and long nose, etc) that caused me to now buy nothing but Knipex. It's the 'little things' I've noticed when using them. Most cannot be seen in a photo. You can hold 'em next to a pair of Channellocks or Crescents, or ...., and never
see much difference - other than perhaps the boxed joint design of the Knipex vs many others, which is also a significant feature.
Start small and find out. A small pair (maybe the shortest) of their trademark Cobra 'water pump pliers' is one tool I'm never without at work. They're always in my back pocket, and are almost constantly being grabbed and used for grabbing / holding all sorts of things, 12 hours a nite. They won't be the last pair of Knipex pliers you buy.
At a previous job (near 20 years ago), a new tech was asking an old tech about the Knipex pliers they were (all?) using. The old tech grabbed a pair of (standard) Cobra water pump pliers, chucked a piece of steel pipe in the bench vice, and 'set' the pliers on it. He told the tech to put as much weight on the top of the pliers as they could, without gripping the pliers at all. I looked down and there was daylight under the tech's shoes, and the pliers never slipped in the slightest. The ratio of the high gripping force of the extremely hardened jaws and the hand gripping force required is extremely high, even w/ the 'standard' model pliers. As you would expect, that greatly reduces hand fatigue, while also allowing increased turning force to be applied to the pliers / work.
As I implied, ya gotta try them and feel them to understand - or your could just accept the web site hype, which as far as I can tell is definitely
not just 'hype'.
EDIT: Just to clarify that those techs I referred to from 20 years ago all bought their own tools, and they were definitely
not making much money, and they were all using those pliers. They were not company issued / provided or discounted or the like.
