I hope you all don't mind me interjecting a few thoughts on AO's.
It seems in general Spydie fans have a pattern of thinking that AO's are more of a toy, or that they just have a play factor to them. I assume we are all talking about just the opening mechanism itself and not the performance of the knife in general. As most are aware here on BF's there are a lot of performance oriented AO's on the market that cut with the best of them. I personally was brought up with the Spyderco round hole, and understand its convenience and performance. With that said, I have also come to appreciate AO's, especially ones with the flipper. AO's can go beyond this play factor, if not Sal wouldn't have continued on with this thread. Spyderco is all substance, they wouldn't go after a knife just from a novelty standpoint.
Conversation with AO's vs. manual folders seems also to gravitate into which version is "faster". Although important in some instances, "fast" isn't always the most significant factor when comparing or deciding on the two styles. I have yet to see or hear of any knife "races". Now I know Sal to be quite competitive, is into racing, and is also quite quick with his hands, so I may be on to something here.
What many can't dispute is that both types of knives can be utilized with one hand, are fast, very convenient, and can be cutting machines. If AO's are not your thing, there are many alternatives for you, but to not want Spyderco to do one seems a little narrow with one's thoughts. I am hoping Spyderco does an AO in the future. As usual, they will bring a strong, "different" pattern to the AO table, which is always a good thing.
I don't necessarily disagree with AO's and their lack of association with the Spyderco name, but the same could be said about the Spyderfly, or even a fixed blade for that matter. Manufacturers do need diversity, and Spyderco is about giving its elu's all sorts of colors and flavors. That is one of the many reasons that they are thought of so highly. IMHO, an AO would bring them a follower or two that has never given them a casual look.
Just some thoughts from an AO and manual action guy, sorry to interrupt.
