Open-Source Modularity vs. Fixed Tool Packages

The Roxon S804 Flex introduces a complete shift in everyday carry tool layout: open-source modularity. Traditional multi-tools, like the Leatherman Rebar and Gerber Truss, use factory-pinned pins that lock your tool loadout permanently. The Roxon Flex uses a specialized chassis with quick-access flip screws, allowing the user to rearrange their own custom toolkit.
