I live in Hawaii and my 3v blade, AD 20.5 is already forming rust spots. So far I got no rust issues with the S35vn blade.

I really like the knife. The shark lock is really amazing. But I have to give props to white mountain knives. I had a problem with my order and they quickly sent out a replacement. Amazing customer service.

One hundred dollars difference between this and the AUS10A FRN model borders on ridiculous, and I can't tell much difference in the FRN and G10. I have the Shark Foot in AUS10A and wanted the drop point style in the same steel; however, the model was switched accidentally when I ordered. Both of these models I consider to be solid, hard use knives with a reliable opening mechanism. For years Cold Steel has used AUS8A steel in many models and, as most can attest, it has held up just fine. AUS10A should be no different. This design is also much easier to maintain than the axis/bar lock - provided you don't launch the spring into space when disassembling. This is a great design and will make Demko a ton of money. My only complaint is with the opener/ramp that will chew on your finger if you get carried away.
