I've got several CRKTs all with blades of AUS-6. Does an acceptable job, mabye a little better than the generic "Stainless Steel" on Brand-X kitchen knives. Edge holding is nowhere near ATS-34 or 154CM but it doesn't, as Bob Loveless says, "cost like the dickens" either which helps with keeping the cost of the knife down.
My CRKT Mirage has a problem with hitting the plastic backspacer which on my knife, soon made a small roll on the edge. By comparison, my Gerber Spectre (154CM) which has the same problem, cut a groove into the black plastic spacer and didn't seem to have dulled the edge much. Hardly a scientific assesment I admit, but does tell a few things.
Anyway, the CRKT Tighe Tac looks like a nice design and I'll probably get one myself.
