Of course AUS8 is a good steel, there's a reason so many high-value blades are made out of it! I've personally found that some AUS8 is better than others, depending on which company does the final preparation and heat treat. My RAT 1 folder takes a fantastic edge, and keeps it long enough for that blade's philosophy of use. I've even been able to shallow out the edge angle quite a bit on that blade with no marked increase in tendency to roll. I've had less luck with SOG's version- the twitch II that I carried for a while required frequent touch ups, and would form micro-rolls after a few pulls through cardboard. I like AUS8 in an EDC folder, but for anything else like wood prep, carving or hard use I'll take a carbon steel or one of the "super" stainless steels that are so prevalent today. For slicing a bit of cordage, cardboard, or lunch items however, AUS8 does a great job and is really affordable. Blows 8CR13MOV out of the water IMHO.
