Paring knife selection for work in the air?
'Air work' is an interesting term that I am not used to hearing, and I do a lot of it. The trick here is where will you be holding the knife as you work. A long thin blade will mean you are holding the blade as you work, which is not a problem, per se.

Small bladed and hook beak knives are well suited for this, as you can comfortably hold the handle. I love hook beak knives for mushroom garnishing, coring, small veg peeling and trimming, etc...

Small straight paring knives are the standard choice for this, if you don't like the hooked blade.
