what is this coating

what is this coating

what is this coating

(OP)
Came across this set of knives and I'm trying to figure out the what the coating is (http://www.stelton.com/ProductView.aspx?id=453)

specs:
material: forged stainless steel
special coating is easy to clean and hygienic
soft matte black coating has superb grip
FDA approved

I did a little bit of digging and came up with nothing, so I thought I would toss it up to the ET braintrust. Any thoughts?

RE: what is this coating

Here is Derncoat from Houts which should be very close to the
one in your post.   I believe you knives have one coating the
whole knife and the grip is a second coating to increase the grip.  The description in several places talk of a rubbery coating on the knives.  This type coating could not be on the blade part.

Houts has a Duracoat system for guns and probably knives.


Lauer has another  Dura Coat.

Rentless has knives that use a Duracoat or Dura Coat type coating.   

Bench Made has 3 coatings for knives.  the number may correspond to the Paraloid materials from Dow.

RE: what is this coating

Hello.  After reviewing the Stetson website, I believe this is a  fluoropolymer-based finish.  Manufacturers like: http://www.whitfordww.com offer non stick coatings for food and military-issued knives.  The non stick comes from PTFE (polytetrafluoroethylene), while the mechanical properties are from the other ingredients in these finishes, binders like PAI, PES, PPS or PEEK.  Ask for Brian Willis.  Whether you want to apply the coating, yourself, or contract the work, he'd be glad to help.

I'm thinking it's unlikely that it's a black-oxide coating. Whenever I get screws with that coating it wears off in no time. These are pretty high end knives and I would imagine such a lack of durability would be unacceptable.

Black oxide done right is very, very durable.
