Polished DLC

[nwmetalbug]

Have any of you guys heard of polishing DLC coating? If you have any info on it please chime in. This is a video of a knife that has the DLC blade polished and im wondering if its the same stuff KAI uses.

That is a pretty finish, reminds me of the brilliant blued finish on the Colt Python/high value revolvers.

This information is direct from Jimmer_5 over email. I can't say if they use the same coating as KAI though. I hope it helps! ~Kirby

To understand this finishing process, you need to know that some finishes are more opaque and others have more of a translucent effect. For example, Cerakote is more of a painting process, and the finish is more opaque. In the case of DLC, the finish is somewhat translucent - this means that whatever finish you have underneath it will be visible. If you beadblast the blade, you will get a matte finish. If you polish the blade, you will get a shiny finish. A shiny DLC finished blade would have been polished beforehand to achieve the shiny black DLC finish.

ZDP has a crazy amount of Chromium. Shouldn't need a coating really. Looks good though.

The DLC coated Rocksteads are YXR7 steel. The ZDP versions are not coated.

The 1600blk has a polished DLC, I've never seen one in person but I'm guessing it's as good looking in real life as it is in the pictures

I've got one of those polished black Chives. It is really shiny.

very cool thanks for the info !

That would be a great treatment for a ZT!

I have a Centofante - this picture shows just how smooth the polish is on the DLC handle (blade not coated) - The handle is so reflective that it looks like it has the same texture as the oak tabletop that it is reflecting.

best

Took a minute to register that it was the reflection, very cool!

My work Blur has become shinny-ish along the cutting edge from use. I think if you put a buffing wheel to it you might get it to shine up some.

Thats an expensive knife, dang

TDLC (Tungsten Diamond Like Carbon) is actually a Tungsten Carbide (WC) coating which is applied by PVD (Physical/Particle Vapor Deposition). This material has an HRC (Hardness Rockwell C scale) of about 72 and a Vickers hardness (Hv) of 1800. TiN (Titanium Nitride) is about 82 HRC.
