Hello! Here are 2 different ways I'm working key management for daily carry. I am working off the idea that the only true EDC REQUIRED items are Keys, Phone, and Wallet. Everything else is an accessory. In that spirit I wanted to make all three items more efficient then they are. This is a modified Suspension Multi-tool. I removed a number of components and integrated nearly all of the tools from both sides into one. The pliers were replaced with keys, and also include a flash drive as well (not imaged). This is a prototype of key management with a slingshot component. I have some other ways to do the slingshot since these images that would make it even smaller. Cheers, H.G.
