Many knife makers make knives with screwdrivers and the like. I'm not entirely briefed on the older styles of knives that if memory serves camillus made, however, in newer knives, as far as I know, you have ruled out the two main styles of knives with screwdrivers and the like. Multi-tools and SAK's, I carry a Gerber Obsidian, it will take a hair popping edge (not sure for how long though) and has a philips and flathead screwdriver built in, it's not the greatest design, not the highest quality, but it's all I can think of off the top of my head that fits your needs.
I make and sell custom cutting boards. Pricing is very reasonable and the worksmanship very good. PM me if interested.
