Hi
Saw that declaration on many of the new line of Camillus products :"Carbonitride Titanium won't flake, blister, chip or peel and is up to 10x harder than untreated steel so the blades stay sharper, longer"

Anyone know something about it? At best it seems like false advertising .
Declaring that tha coating " hold " the blade stracture similar to an argument the paint holds the house walls from collapsing .

correct me if I'm wrong,

CNT or the older TiN coatings are not like paint at all. They are molecular boded to the base material for a few thousands of an inch kind of like aluminum anodizing, which makes them unable to be chipped off, flaked, or peeled. the only way to remove them is by material removal deeper than the coating ie. grinding or cutting. But, that means not very good for being resharpened w/o loosing the coating.
 
I don't claim that they are like paint, I claim the coating cant hold the structure of the blade like paint can't hold house walls; this Carbonitride Titanium coating may not chip, but the blade CAN chip.
The advertising is a bit Foggy and people might think that those Carbonitride Titanium coated blades are some sort of "superknives"....
 
About the best I can do is roll on the floor laughing. It sounds good but is complete BS.
 
seeing as the stuff supposedly has a theoretical hardness around the 85 HRC range, their 10x harder claim must be referring to fully annealed steel...lol
 
I had one of the Camillus knives (surprisingly nice), and the coating was not on the actual cutting bevel. It most certainly doesn't improve edge retention :p
 
The Titanium Carbonitride (TiCN) coating Rockwells in the mid eighties on the C scale. It is a Particle Vapor Deposition (PVD) coating that will protect the blade from corrosion and scratching. The Rockwell scale is not linear. 80 HRC is not 1/3 harder than 60 HRC. It is more than 10 X harder. You can use the coating on the flat sides of the blade to steel the edges of your steel blades.
 
If they did the TiNi bonding AFTER it was sharpened then maybe the high RC of the coating would make for longer edge retention, but since the edge is uncoated the TiNi has no effect on sharpness whatsoever.

Covering the sharpened edge with what would be considered a thick coating would make the edge very blunt.

Where did you find this information? I have been looking around, everything I can find about the testing method suggests that it is linear
