DLC / Coated K390

#1

Post by electro-static »

I bought the BladeHQ DLC coated M4 delica and love what the coating it does for corrosion resistance and ease of cleaning. I love K390 and couldn’t think of a better thing than putting such a coating on the K390 seki spydercos to enhance ease of maintenance.

Is there a reason why we don’t see coated K390 Seki spydercos?

Seki and Taichung use TiCN, rather than DLC. AFAIK, TiCN is not as good as DLC from a durability and corrosion resistance standpoint, but is still better than no coating. If you like TiCN, you're gonna love DLC :)

I too am hoping they do a run of the current Seki K390 lineup with coated blades.

I love my coated M4 delica. It’s kicked my K390 endura out of my pocket on account of the ease of maintenance. I can put it away dirty and not worry about rusting out the pivot

I agree. I’m borderline phobic about the risk of corrosion but my coated M4 Native is my favourite work knife. I have the coated 4v Goddard, too, but would love some coated k390 and maxamet.

You can get your blades coated with DLC at hvm.cz (by HVM Plasma) they charge $8usd per blade plus shipping. They can coat your liners if you desire so. You can check out their work on facebook group Spyderco CZ/SK, due to relatively low cost, lots of the blades in Czech are being coated there

Do they do regrinds as well, also what temp do they go up to?

Not needed

Also in my experience coatings create drag when cutting

Lots of available steel that corrodes less

But I view my knives as tools

The coating process interferes with the blade temper. It might be possible to do on K390 but requires more R&D.

Polished K390 with DLC would not create drag and would be highly desirable. Look up polished DLC. It rocks

That is a reason that makes a lot of sense to because K390 doesn’t use a high temper for knife blades like it does for high speed tooling.
