“Smooth jaw” should be smooth jaw. There should not be any questions here. It clearly slipped through the cracks or the seams. A file or Dremel tool or sanding tool or other should be able to make it pretty smooth pretty fast.
I want to know how these look in general, before going into a long return and buy again cycle.
And I still hope people share how it looks on theirs, I have not seen any talk about this matter before.
oh
but you still will not know what you will be getting, if you re order
it;s kind of a long shot that more than 1 or 2 people on here will have these exact pliers
Any size in this series is good info for me like I have said before, I may want to order other sizes too, in fact that is what I wanted.
These series of pliers are quite popular, not sure why you imagine only 1 or 2 people having them.
The V jaw type are so much better at everything. If you’re worried about scratching things, put some electrical tape around the V jaws before you attack anything that you might scratch. Or like I said, make it smooth yourself. If you don’t have tools to do it probably know somebody that does. And they will tell you to get the v jaws.
Like Oli said, if you don’t want to scratch something, you’ll have to use a barrier, like paper or tape or whatever. This would be the case even if both surfaces were ground.
Total noob here and first time posting but I do own a set of 86 03 250 (same size without the comfort grip handles) Knipex pliers wrenches. I don’t know if it’s clear in the attached pictures but the upper jaw is forged with a machined surface. If it didn’t get machined, there would be a parting line through the gripping portion of the upper jaw. However the lower jaw doesn’t have any obvious secondary operations. My thoughts are that it is investment cast. Either way it’s not as rough as the lower jaw in the set you received.
i have ~10 knipex PWs, and the surface finish on the jaws of OP's pics are within the range of what i've seen. it's normal imo, but funny to see both on one tool.
besides, after use, they will get a bit chewed up and will have bigger surface defects than that.
It looks like neither the top nor the bottom pieces are forged as you can see the parting line of the pressure casting mold and the taper or draft in the side wall of those “strengthening” holes in the lower jaw. Likely the flashing was unsightly and needed to be ground off the top jaw.
I see that faint seam there in the middle along side the length of the jaw.
That is what was so raised on the first Knipex I have bought that was only clamping with the seam, the not whole plain of the jaw.
Interesting the process is not the same on all these lower jaws, some have the seam some only have some rough “casting” surface?
