Coated Blades and Lock Rock/Slip

[jstn]

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.

It's fine to avoid certain companies for aesthetic reasons, but you said companies who coat their blades "aren't quality to begin with". That seems a bit premature, presumptuous, and preposterous considering almost all top production companies (ZT, Spyderco, Benchmade), midtech (Les George, Hinderer, Strider, etc.) and even many custom makers coat their blades. I often steer away from coated blades because I don't love the looks, but that doesn't take away from the quality of the companies. I certainly hear you on coated blades looking cheap though!

I have, and have had, a number of coated blades and have had nothing such as slippage, or lock rock to happen. I just cannot buy the no quality about coated blades, I hate to break it to ya' but Hogue DOES make quality blades. But I understand where you are coming from Hwang, and you are right about knives meeting your own standards because we all have certain things we like in a knife and certain things we do not like. That is our right!:thumbup:

Process or coating...same difference to me if it's applied to the blade...

Actually no, not the same, PVD is the process used to apply the coating. TiN (titanium nitride) is a commonly used coating that is applied using PVD but there are several other types of coatings applied using the PVD process as well. It uses a beam of plasma to vaporize the material and blast it into the surface at extremely high temperatures in a negative pressure atmosphere.

To call a coating simply PVD is inaccurate, as PVD isn't a coating type at all, it's the way the coating is applied. I'm not aware of a company that claims its blades are "PVD coated".

seen it before other places too, though that could be more of a translation issue more than anything

Plasma sputtering is one method of PVD. There are other methods as well.

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!

LOL, perfect sig line right there!:

Yea should have included that info, tho I couldn't even begin to name a single other method used...

Not that its useful for the coating of anything really (tho I'm sure it's often used on knives lol) but technically the process to make fingerprints visible where they heat super glue into a vapor and then it deposits onto the oils in the print is a form of PVD.

I don't think they're necessary calling the name of the coating "PVD coating" (also some of the names of specific types of PVD applied coatings are trade marked and they may not have permission to use the name for advertising) but simply saying their blades have a PVD coating of some sort (that again they may not be aloud to use the name of their exact coating in advertising, or they simply don't want to/don't care to inform their customers). It doesn't read "the blade is coated with stuff called PVD coating", it simply lists PVC coated as a spec.

splitting hairs aren't you?

Correct, but let us not insinuate that your standards are the norm, or the only standard that might matter over all. That is how you are posturing yourself, in a very prepotent manner.

If you seriously think this thread is bad, you haven't seen anything yet. Word of advice, stay out of Whine and Cheese!

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.

If the lock is designed and built right, the geometry and material strength alone will be sufficient for lockup even if the contact point of the lockbar and blade had zero friction. Wear, insufficient lockbar strength/hardness, poor design, a grinding error on the blade tang, etc.. these things might make a lock that would seem stable with no coating be more prone to failure with a coating or lubricant there to reduce friction.
