Hey Fireincairo, awesome pick on your knife. I have the S30V version and it's one of my personal favorites.
To answer your question about the anodized finish, it is pretty tough in my opinion. It can get dinged and scratched up easily if you have your keys in the same pocket though, so I would recommend carrying it separated from anything hard enough to beat up the anodizing. Otherwise, it seems to last pretty well, although I also heard you shouldn't clean it with hydrogen peroxide, which will apparently screw up the finish.
Also, if your looking for more knives with your requirements, look at the Benchmade Mini-Presidio and the Mini-Presidio Ultra. Both are awesome knives and are extremely tough. The Ultra comes with 440C and Noryl GTX handles, compared to the regular with 154CM and anodized aluminum, but its way cheaper and is an awesome deal. My fullsize 520 Presidio is seriously one of my favorite knives aside from the 940, and it is tough as hell, and looks pretty cool too, you might enjoy one.
