I would guess to more closely mimic the full size. Having now carried mine for a few days, I find I do appreciate the scallop. It does improve access to the stud. Adding one to the Air Lite handle design seems reasonable.
Since it's new, I'm still carrying the mini-recon 1, now with proper edge. The thickness immediately above the primary edge bevel runs about 0.040"; so I decided on a compound edge. I thinned the shoulders using a 15 dps setting, then used 20 dps for the cutting edge. Since it came with a considerably coarser edge angle than 20, and with that blade thickness, it took a bit to remove that much metal, even using the extra-coarse DMT stone. But I'm happy with it now.
With a proper edge on it, now I'll see how it works for me. I do like a bit of thickness behind the edge for every day usage. For me, "great slicer" is an overrated aspect for an EDC. I don't slice a lot of cardboard and I don't use a pocket knife for food prep. So "slicing" is seldom necessary.
