My comments moved from the poll thread, edited a bit for here.
I agree with this being a dressier type of knife, a gentleman's knife. Thus, even if there were a salt version of it, I would not choose an Air over a Salt or Caribbean to take to the beach. So, I'm not sure a salt specific version is needed. Thus, while a bright handle may be interesting, it may also clash some with dressing up unless the material sufficiently compensated for that. So, I prefer the idea of a more neutral color. Anything from light gray to the black/ebony sounds good as long as it looks classy and isn't slippery (like my Caly 3.5). As for the steel, I like many different steels and am not too particular there. Should it be the same as the original, or possibly upgraded a bit? I wouldn't mind a Magnacut version. I don't have any Rex121 yet, but also like my Sage 5 Maxamet.
As for the clip, when dressing up, I would never hook a clip on my suit pants. So, if a clip were to be included, I would like the knife with the clip removed to still appear complete and not
missing something. Perhaps a different type of clip would help.
I have a little Boker Barlow slipjoint where the clip screws into the end of the handle.
Removing the clip exposes a groove, which is not as pleasing.
With the Air 2, a clip could be similar, but without that groove. The standoff would need to be moved a bit more toward the end of the handle so the clip does not protrude from the edge too much as it wraps around the end. As with the little barlow above, the clip would not have a screw on the main side of the clip. Instead, the screw could be into the standoff on the opposite side. The clip would wrap around the end of the handle. The standoff screws on both sides would need to be long enough to work with or without the clip. Instead of having a flat area at the end of the handle like the barlow, the end of the clip on the Air 2 could have a small tenon (detent?) that fits into a small hole near the standoff screw. That little tenon or detent would stop clip rotation when the screw was tightened. That single small hole would be much less noticeable than either the wire clip indentations or the triple screw holes. The result may allow the Air 2 to look finished/complete with or without the clip and the clip would work for tip up left or right carry.
