My general understanding, is that Type III hard anodize is the most durable form of aluminum finish. Correct?
I also understand that as such, the metal doesn't take colored dyes, like other less durable forms of anodization.
So, does anyone know whether:
A) Microtech uses type III for their black knives?
B) Are the colored variants any less durable?

Thanks!

Pretty sure all of them are type 3 hard anodized, black and other colors.
 
Thanks for the feedback. Maybe so. I guess I'm just used to the gun-world, where type III hard anodized aluminum parts are always black. But then again, there's always the ninja factor...
 
If they're referring to MIL-A-8625 type III class 1 or 2, then it's a specification for a type of hard anodic coating

Class 1 is natural/not dyed (most common AR-15 upper/lower receivers use this finish.)

Class 2 means that it is dyed/colored (typically black.)

I don't think one dye color is more or less durable than another. See 3.7.2 here:

I have a Hera II Mini and the finish seems to hold up well. With the sole exception of where the ball on the clip touches the body. That spot was the finish worn off. Not that you can see it with the clip installed.
 
Thanks, guys. It's hardly the biggest deal; at the end of the day, it's a pocket knife...not an heirloom.
But I was simply wondering whether the constant friction from deploying the blade, would have a more noticeable affect on the colored metals, versus the black. But sounds like it's fairly negligible.
