Coated Blades and Lock Rock/Slip

[dwdickey]

Did a cursory search but didn't find anything... as the title states, are fully coated blades (DLC, PVD, Cerakote, BK1, BK2) more susceptible to to lock slip/rock than their non coated counterparts? Specifically speaking in terms of liner or integral/frame lock style locking knives.

None of my coated blades from various manufacturers have any kind of lock rock/slip. That includes Emerson, Benchmade, Spyderco and Zero Tolerance. I'm not sure if you know this, but the part of the blade that touches the lock is not coated.

Perhaps, but I'm thinking companies that coat their knives in the first place aren't quality to begin with.

I.now avoid any knife that is coated, not for blade play reasons, just looks cheap.

Coatings like PVD or DLC are definitely not cheap. They are also pretty durable, but will wear when cutting abrasive material (but that would butcher the finish on the blade anyways).

PVD isn't a coating, it's a process, Physical Vapor Deposition.

Kershaw, ZT, BM, Spyderco, Cold Steel, Emerson, hogue, Rockstead, Grayman, Hinderer, Becker, Esee, and leatherman aren't quality to begin with?...

The coatings are usualy ground off of the lock faces so there is no coatings there making it a metal on metal contact.

Process or coating...same difference to me if it's applied to the blade afterwards for appearance or other reason I consider it to be a coating.
I have at least 3 different examples that have coated (DLC) blades Microtech, Spyderco, & Kershaw all 3 have the blade tangs coated...
In at least one example I can get the lock to deflect as much as 40% towards unlocking (it's normally at about 50% lockup), so far it hasn't actually failed but it'll come darn close.
Just thought it was odd.

Show us some pics of those coated lockfaces please

I find this hard to believe without pictures. If you have trouble uploading them, I'll gladly put them up for you. Just e-mail them to me.

The only knife I've had lock slippage is my Emerson mini 15. It is a coated blade but thats not the cause. There's noticeable deformation on the Ti. I've been meaning to send it in, just haven't yet. Been carrying other folders lately just put it on the back burner i guess.

This is by far the most idiotic statement I have ever heard on bladeforums, and I've seen some really stupid things written on here. Congratulations!

My 2011 Microtech SOCOM Elite was coated on the lockface but had no lockup issues. That was a magnificent knife and I miss it.

 

[Spyder328]

The lock faces on the coated PM2s are coated. Mine had a lot of lock stick till it wore in

 

[dwdickey]

Heres some of the lock slip I'm seeing.
Normal state ~50% lock up at rest:

Moderate spine pressure lock up is 10-20%:

That's a thinking that's going to get you far...

Why don't you call Matt Diskin:

The good folks at Rockstead:

Spartan Blades:

And let them know they don't make quality stuff...

^Interesting on the black Military. I have the same knife, and the coating was grinded off http://imgur.com/zfFTpm9 (linked because the pic is pretty big)

 

[KnottyEagle]

Have you checked to make sure the lock face and blade tang are free of any oil or debris?

 

[fzla226]

Spyderco Manix 2 XL DLC coated definitely has DLC coating on the lockface, but there's no stick/slip of any kind. Oddly the coating is stripped or wasn't applied at all to the area on the tang before the lockup and it's nicely polished.

It's my choice to avoid certain styles because to me they look cheap regardless of quality. I'll simply buy the non coated version, if no option, then no sale.

I already have a coated blade by hogue, it's not quality by my standards.
