Hi folks.

I'm new here and was looking for a thread about Black Ti coating but haven't found one. Can't use the Search feature.

What are the advantages of Black Ti? Any disadvantages?

Thanks.

It is very durable, only Boron Carbide is better to my knowledge. It prevents blade from corrosion and probably from scratches. Also Buck polished TiAlN just looks great:

Thanks, Vassili.
 
If its Flat Ti then it the blade wont be reflective or as visible say were it a lighter color in certain situations, which may be a huge advantage to you depending on your needs etc.
 
When on a ninja mission your blade will not be reflective which could cause you to be discovered and tortured endlessly and could really hurt. :D
 
I've never seen a flat TiNi coating. I'm sure someone will correct me if I'm incorrect, but "flat" coating is usually DLC (Diamond Like Carbon) or guncote or the like.
 
No advantages what so ever, reduces cutting ability no matter what you might hear. It is however preferred bt most mall ninjas and recliner commandos.
 
Welcome to BladeForums!

To me, whether there is an advantage to a coating depends on what alloy is being coated. It seems reasonable to me to coat a non-stainless steel or to coat a stainless steel that is going to be used around salt water all the time. A coating on such a steel improves corrosion resistance. For stainless steel in a non-corrosive environment I see little advantage although as Esav noted, it looks purdy.
 
This is usual TiN coating - kind of matte:

How can it possible reduce cutting ability???

Thanks, Vassili.

Top high carbon stainless steels can corrode as well, slower then carbon, but they will.

Another TiN on A2 steel, where it is very needed:

I am not worry if someone will say that this is mall-ninja knife, I know that this is all grate knives and really durable, good looking coating makes it just better.

Thanks, Vassili.
 
Mostly it's just darkening the blade. Teflon is supposed to make the blade easier to extract, plus it protects the blade to a degree from corrosion.

The titanium finish is just cosmetic, but it's probably tougher than Teflon. Buck's finish is very nice. So is Gerber's finish on its AR 3.00 and Cold Steel's finish, but they scratch easily.

Teflon is really easy to scratch not TiN, TiN is harder then steel and usually it is not a scratches but marks which eventually washed out (if you try scratch it with let say keys or something).

Thanks, Vassili.

How does a coating that is only a few thousandths of an inch thick reduce cutting ability?

TiN is used on Motorcycle forks and shocks to reduce friction, so it would seem to reduce friction when cutting some materials, also.

Welcome to the Forums, Bill S.:)
 
No matter what you hear, it will significantly reduce rusting. I've personally never noticed, nor can I image anyone noticing a difference with it with regaurds to cutting ability. It and other coatings are a very functional option to have.
 
Advantages too numerous to list. Suppose you are on a mission to free a guy being held in an enemy camp. You've got your blade out and approach the sentry from behind. The moonlight catches your satin-finished blade and is spotted by a someone in a guard-tower. Suddenly the night is alive with AK-47 fire, all coming in your direction. Not good...

Or, suppose some blood spatter from your most recent covert de-animation activites has gotten into your blood groove and cause some corrosion. As you pull your blade from the tactical sheath, which is festooned with enough 550 cord, snaps, and fastex-type connectors to encircle the globe, the blade catches on something. Due to the corrosion, the blade has weakened, and it snaps in two. Again, not good...
 
any coating will scuff and scratch, believe me, i have knives with bodycotes diamond like finish (or something like that) and it will scuff right with the rest of them..

i dont like coating on my knives so i would say any coating offers -0- advantages unless ya live on the ocean, then maybe i could see it, maybe, even then if ya take care of it it wouldnt be neccesary.

And I have all this and TiN and BC - this two is much harder to scratch, they are more durable. DLC is amorphous carbon as I heart but it is softer then TiN and BC.

Thanks, Vassili.
 
Thanks for all the replies! Great photos, too.

So far I have only one knife with Black Ti -- a Benchmade.

I haven't used it for edc, but I may start.
