Repair limitations with DLC coated blades.

[toker]

I don't plan on prying with the blade, but in the event of an accidental drop, losing the needle tip on these blades is a real possibility. Am I missing something?

Not missing anything. But unless you constantly look at the spine of the blade, you probably wouldn't notice that it's missing the black DLC coating in the case of a regrind. Not to mention that it's a tool at the end of the day, not a museum piece.

I got to thinking maybe he’s worried they’ll regrind the whole front end, but at that point the cost from a 3rd party wouldn’t be worth it and the manufacturer would replace the blade or reject warranty, not regrind the sides.

Most likely

If I break a tip on one of my PM2's it will be the new "custom" chisel-point/screwdriver/full-flat grind I've always wanted and I'll just say Sal made it for me special-like.

A strange thought came to mind when considering purchasing a DLC coated Paramilitary 2.

If the tip was to break off on this knife (or any DLC blade) would I be stuck with a knife that cannot be fixed as the coating cannot be (or wouldn't be cost-effective to) be reapplied to where it is fixed?

Hence having a black bladed knife with a shiny tip.

Really depends on how much tip is broken off. I have actually had this happen on a Para 3 that was accidentally dropped and lost its needle point tip. Just carefully re-sharpened it to reform the tip without needing to affect the spine at all, thus making no difference to the original DLC.

However, if you were to pry and end up with major tip breakage, my guess is that you would actually need to re-grind the spine to bring back the tip. This would take the DLC off the re-ground part of the spine. Don't bother with re-coating as DLC is an industrial application process that is volume dependent; just live with the shiny spine and continue to use the knife.

If I overthink in advance such hypothetical situations, I’d never buy a knife.

It's just one of those things that comes with the territory of coated blades. Most people either love them or hate them. I've bought all uncoated blades in the past except for a few smokin deals that I couldn't pass up because I prefer satin blade finishes and because I know the coatings will always wear eventually. That said, on the few knives I do have that do have coated blades, I like to watch "patina" as the blade gets some scratches. And honestly, they all end up lasting much longer than I thought, and look better than I imagined as well.

DLC isn't hard to get off. Diamond stone does it just fine... I did it to my smkw Kershaw Bareknuckle. I dig the look though. It looks very well used.

Wouldn't be hard on equipment at all, as long as diamond or cbn abrasives are used. Or even silicon carbide.

I did break few tips on my knives, M4, S30V and 154cm. All of them were un-coated and all of them had only about 1/4" piece missing if not less.

If the blade is coated, the easiest home fix is to round/pick up the line, of the cutting edge up, to the spine of the knife, then sharpen it.
This way, if you are careful, you won't scratch the coating of the spine of the blade and you'll have decent curve of the cutting edge with slightly shorter blade.
The DLC coating on both sides of the blade won't be harmed either.

By the read, it is my assumption your concern is related to aesthetics vs. performance. Don't let aesthetics get in the way of a resolution.

The owner was very pleased after I removed some of his black coating on this project. Sometimes we need to think outside the black-box for a reflective revelation ;-)
