My guess is that making an expensive custom mold for the Res-C handle drives up the per-unit cost of a blade, unless they can spread that cost over a large product run, like a big military order. Cord-wrapped will help on the price-performance ratio for lower volume runs.
I was thinking completely opposite. As an example, take the regulator handles. Once designed and mold formed, assuming you could keep the tang design as a "constant", it seems like you could now use the same on this blade (as an example...not saying I would prefer it). Then you could end up utilizing one mold across multiple designs and spreading the costs even further. Whereas...a wrap continues to incur either machine / human time for production, and would seem more expensive to me. I guess it really comes down to volume...and I don't have insight to the SYKCO numbers to begin calculating it out.
