I think there's a fine line between a comfortable handle and one that looks comfortable but isn't. IMO, the BM Griptillian and Presidio/Bone Collector are some of the most comfy FOLDERS I have ever used. You can really push them hard and it will not (the aluminum Presidios have those hard scallops but the Ultra series are really nice) dig into your hand or cause discomfort. An example of a knife that to me, looked and initially felt comfy was the CS new-gen Recon1. All those finger grooves, what's not to like? Until I was doing some experimental wood carving to make a wedge for a project, wow that handle really wasn't made to lean on. For me, if the handle scales are flatter, I want something more neutral in shape. I have a new gen CS Voyager with its more rounded handle profile, it is a comfy knife in use as well.
