Another vote for the RAT II. Not sure if it was mentioned yet, but it uses AUS 8 for the blade. I like it because overall the knife is very thin, and the blade is well centered and smooth to deploy. Great quality for a $25 knife. I bounce between the RAT II and a Benchmade Griptilian with a 154cm blade. I like the RAT II just as much, and it costs 4x less.
