In case you aren't aware, Hogue is making knives now--they're the OEM for SIG's line of knives (I have one of their K320A autos). Funny thing; I'd been seeing them for a while, but never put the knives and grips together until the Knife Center had one of their execs on their YouTube channel at the Blade Show last year and he mentioned the grips...My second knife would be a Hogue revolver type finger grip. Not really what you are after but it is my concept.
