Same experience here, the coating has held up to slicing duties (paper, plastic and packaging), of EDC. Would not hesitate on another DLC coated Spydie.

Are you talking about more of a scratch or a chip? Would love to see a pic if yours is actually chipping away. Here's a pic of the Aegis I referred to in the video that had a big scratch on it:

I didn't watch the whole video - but most of it ("coating" length of video).
DLC is a finish I believe primarily done by IonBond. It's superior to virtually 99% of all other sort of finishes out there, only from the fact that it does not impregnate itself into the steel like some even more expensive coatings do. It has a Rc in the upper 80s and can be very easily cleaned with windex or some form of cleaning product. (To get rid of the oil residue near the opening hole).
The finish takes its appearance based on the finish of the blade before application. If the blade was blasted with fine media, then DLC'd, your coating will have a micro-"sparkle" effect in direct sunlight (and sunlight only, and this can be seen on any DLC'd Kershaw / ZT blade from my experience). If the blade was mirror polished, then you'll get a polished effect, satin - a satin effect, etc. I don't know how Spyderco finishes the Para2 but that's how the coating will look upon application.
Many higher-end firearm manufacturers or customizing places do offer DLC coatings for parts (and those see TONS of wear) and it's one of the best. (I believe the Springfield Pro used by the FBI utilizes a DLC coating)
Here's some info I found from a link from a 10-second google search:
Another SUPERB coating for ferrous alloys (in this case AISI 4140 and 4340) and stainless steels (in this case 1740, 415R and 416R) is the plasma assisted vapor deposition coating called Tungsten Diamond Like Carbon.
It, like Titanium Aluminum Nitride, is one of the newer coatings for us firearm enthusiasts and is virtually impervious to just about everything your pistol or rifle will be exposed to.
The total thickness of the coating is approximately 5 to 7 microns.
I have numerous articles in which I will add to this thread in the same manner that I did on the TiAlN.
I have a second Springfield TRP that is being coated with the W DLC coating with Ionbond as a test sample. I'll post photos and testing results. I can tell you now that I don't expect ANY issues with the coating.
One advantage is that the temperature for the coating application is approximately 300 degress Fahrenheit from what I've gathered from an exhaustive literature search and speaking with a gentleman in the industry. Compare this to the 900 degrees Fahrenheit for Ti coatings. I like 300 degrees over 900 degrees - even though 900 degrees doesn't negatively effect 4140 or 4340.
The W DLC coating will be black not charcoal, but it can be had in many colors depending on the process. In this manner Titanium Aluminum Nitride and W DLC are, again, similar.
There is an excellent SAE Paper Titled SAE 2002-01-3296 "Racing Applications and Validation of a Hard Carbon Thin Fim Coating" that essentially acknowledges WDLC being used in NASCAR engines. I can state - without divulging anything else - that NASCAR is NOT alone in this regard. The photos of wrist pins, cam shafts and surface topography specimens must been seen to appreciate.
Some properties:
Hardness: Typical 1500 HV (btwn 800 - 2200 HV specific application)
Young's Modulus: Typical 200 GigaPascals (btwn 150 and 250 GPa)
Coefficient of Friction: 0.1 to 0.2 Against Dry Steel
Max Temp in Application: 662 degrees F
Deposition Temperature: Less than 302 degrees F
Coating Thickness: 1 to 3 microns
Color: Dark gray-black
Adhesion to Steel: Excellent

Whew. Long, techy post. Hopefully this information was helpful. Bottom line is: DLC is basically the best coating that has been used in production for knives, bar none, for wear.

My para-2's coating hasn't really worn that much either. I use this knife pretty hard and regularly and have been really impressed with the wear on the DLC coating. The DLC is wearing off around the thumb hole. I think this is pocket wear... The edge chipped quite a bit in the beginning but is hasn't since i've re-sharpened the knife which continues to maintain an impressively keen edge. Personally I like the compression lock and that it isn't under my first finger when bearing down on the blade. It feels out of the way but sturdy for the size of the liner stock....

knivesandguns- My guess is the S30V was blasted instead of polished although I wouldn't necessarily call it a sparkle in direct sunlight. It does get a little bit of a bronze look in direct sunlight and the "pebble" look is more obvious.
