I would buy that sharpener. I'm guessing Sal has probably contemplated something similar to what you're dreaming of. Lots of sharpening rigs out these days though.
Favorite(s) for different reasons are the top three in the picture.
Caly 3 was the first folder I bought, and it's the knife that got me hooked. Beautiful ergos, steel and cf. The quality of it is what got me, I'm sure if it dulled and fell apart I'd have given up on folders, and put an olfa back in my pocket. I carried it daily for over a year and it held up beautifully.
Domino, great design and build quality. Very fun to flip and flick, I really like the cts-xhp, and the blue cf is a nice touch.
Slysz Bowie is just an all around great frame lock folder. I love the simplicity and just how it feels and operates. Very nice finish on the handles and blade.
Spyderco's that I'd like to get next... quite a few actually

There's more, there's always more.
Dream knife, I'd like a caly 3 Damascus bolstered. It's been done before, but they're hard to find these days. Sort of a tribute to the knife that brought me into the knife world.
