I'd love to see a Cub Scout style knife built on the GEC #66 pattern. Main clip or spear with a caplifter/screwdriver behind it, and a punch on the other side.
The Indian River Jack is one of your best sellers and Queen already makes punches, caplifters and can openers. A full-on Scout knife on that IR Jack frame would be sweet. My son has a S&M Jr. Scout, but a full-sized version would be sweet, too.
