This is an idea that comes up from time to time, back a few years ago Kickstarter was endemic with them. Seems that no established knife brands have really pursued the idea. Most of the tools I've seen them over-designed or over-engineered and built to appeal to redditors more than any other user base. Buy, blow-up your media accounts with pics, and then toss in a drawer or use as a desk toy.
Toler Tools Union and Yanko Designs are two I recall because their accounts followed me on Instagram recently (which I blocked, not a fan of corporate accounts). Search for them or "modular multi-tool" and you should be able to get a good grasp of the market and what's available.
