I'm fond of Arcs but what is this statement based upon?
HA-III is HA-III is HA-III.....
It either is or it isn't.
When I hear quality control I think about color consistency and in that department Arc can't even see SureFire's taillights.
My $0.02.

This statement is based upon having worked in a production plating shop. I done all types of anodizing. Everything from Hard Anodizing, chem dip, clear to color anodizing.
I'm quite familiar with quality controls issues of anodizing and color is not a true indicator of quality HA. IMHO Surefire has the best HA quality controls in the business, with ARC being the only other mfg at the same level. Don't let color fool you, it could be dyed.
There is no non-distructive tests for HA, unless you have access to the bare part before anodizing. Quality HA is at least 1mill. Ask PK, I bet he'll verify Surefire's HA is at least 1mill.
There are several different tests that I won't go into, but the easiest is the scratch test. HA has a rockwell of 63+. most quality knives have a rockwell of 59.
Take your ARC AAA out and try to scratch with you knife. If it penatrates then the HA is thin. If it bounces off, then you've got quality HA. test takes some gall /ubbthreads/images/graemlins/grin.gif
