"Atramentized" or "chromed" Knipex pliers?
"Atramentized" or "chromed" Knipex pliers?
Knipex doesn't provide much information, unfortunately:
"What does it mean that my pliers are 'atramented'?"
Atramentizing is another term for phosphating and is part of the concept of rust protection.
Atramenting alone, however, usually does not provide sufficient corrosion protection to keep the pliers rust-free for a long period of time.
It is perfectly normal for this layer to wear permanently in the area of the cutting edge. The phosphate coat is an excellent primer with a coat of varnish applied over it.”

I've heard numerous pros and cons for both, which I'll try to summarize here:
Chrome plated (chromium plated) pliers can have thin "flakes" of chrome that can come off with heavy use, although I'm not sure if this would apply to these pliers, especially if the plating is super thin and therefore , cannot form such an incoherent surface.
Atramentized can be more prone to rust, although many report small rust spots after years of use.
For the toothed pliers version, the Atramentized pliers can grip the object much better, because the chrome plating makes the teeth a little more "smooth" (chrome plating reduces the "height" of the teeth because it "fills" them with material during plating).
I've heard that if there is extreme use and burrs form, the chrome pliers can't be deburred that easily because it will remove the chrome layer itself. The Atramented, on the other hand, can be deburred. However, chrome is apparently a harder metal, so a chrome-plated pliers may be less likely to damage easily.
A chrome plated pliers can also be slippery compared to an Atramentized one when trying to grip a nut.
It's just an opinion, but I look forward to your comments.
