Thinning a DLC Blade

[Manifestgtr]

My DLC Shaman has seen 5-10 sharpening sessions at this point and each time I get this feeling like I’m edging closer to a “situation”.

There will come a time when the thickness behind the edge becomes too much and it NEEDS to be thinned. How do DLC users deal with this? Do you have to just kiss it goodbye and take it to the diamond plates (something I’m not against since this is a user anyway)? Are there other options I’m not aware of…specialty bladesmiths, Spyderco themselves, etc?

I’m not huge into DLC and this is one of the reasons. Geometry is just such an important factor…

Well, you could try just creating a large back bevel. But if you're determined to thin out the entire flat grind and still want a DLC blade... you could grind it, then send the blade somewhere to be DLC coated. Although for the cost you may as well get a new knife?

Same way I do with any other blade. Thin the back bevel to the 10dps ballpark then microbevel. There's nothing different about doing it on coated blades.

On knives with thick baked on coatings like ESEE's and that SRK, there will be a small transition area from the bevel to coating where it's worn off a bit. DLC is extremely thin so it doesn't have that issue.

That's what I was thinking- just change the main bevel and end up with a larger silver stripe along the edge.
There are people who regrind blades which of course takes off the coating. I've seen some that looked good where the reground part was now silver but the original flats were black, in the same way that some custom knives these days have satin finished bevels and hammered flats.

I sharpened into the DLC on this one. I've never noticed any negative effects from it.

Thanks guys. This is PRECISELY the info I was looking for

Yep what Vivi said! I reprofile a coated blade the same as I do an uncoated blade
