dlc coating

It is said to harden the surface up to around 80-90 but my experience is it will mar no matter what if you really use it. I have stopped buying coated knives for that reason and because my tastes have changed but I think DLC is one of the best factory coatings going from my experience.
 
I am no expert, but from what I've read DLC is the best. It is super hard but so thin that if you scrape it w/ enough force, it will be defeated. I've had a few DLC-ed knives and never had them scratch, but I don't use for digging & such.

I read a couple years ago that Kahr pistols decided to make a black pistol after requests from LE customers. They did extensive testing of coatings, and found that DLC was the best, especially I think in terms of scratch resistance, so that is what they decided to use.
 
thanks for the info.. purchased a peter atwood tool with this coating, just wondering how it would hold up to edc.
 
IMHO it is way better then epoxy and teflon (this two not really durable), it is similar to TiN, TiAlN and BC, but slightly softer then all of them. However it is not really too different for practical use.

Thanks, Vassili.
 
it will scuff/scratch i have 2 with it FWIW, not as bad/easy as some, but it will scuff/scratch with use.
 
Any ideas on how to restore it or at least cover the scratches/scrapes well enough? I like the look on my RAM, but I slipped while sharpening on 200 grit sandpaper, and there's a lovely shiny idiot mark near the spine now. There's always the black Sharpie, and I might experiment with some black spray Duracoat if any of my gun geek friends ever grab some like they keep saying they will. Still, I'd like to keep actual DLC on it if I can.
 
Having belt sanded a few Kershaws to completely different blade shapes, I can tell you its very difficult to completely remove it.
 
Oh wow, I thought I found a recent thread. Oops. Sorry for bumping one that's a year-old today!
