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.
How to Read Multitool Specs
- Blade steel: 420HC is a stainless steel that is easy to sharpen in the field, with moderate edge retention. 154CM, used here for Leatherman’s replaceable wire cutters, is harder and holds up better against repeated cutting of wire. For a deeper comparison, see our multi-tool blade steel guide.
- Locking: A lock keeps a tool from folding onto your fingers under load. Check that every tool you will push on (blade, saw, screwdrivers) locks, not just the main blade.
- Weight: Under about 8 oz is comfortable for daily belt or pocket carry. Heavier tools make more sense in a vehicle kit or tool bag.
- Replaceable parts: Replaceable cutters or bits extend a tool’s service life, because the parts that wear fastest can be swapped instead of retiring the whole tool.
Which One Should You Choose?
- Leatherman Rebar: The lightest here and a proven all-rounder. Choose it if most of your work is plier-centric and you want replaceable hard-wire cutters.
- Roxon Flex: Choose it if you want to decide which secondary tools you carry rather than accepting a fixed loadout.
- Gerber Truss: Choose it if you want tools that are reachable from the outside without opening the pliers first.
Before You Carry
Locking blades are restricted in public places in some jurisdictions. Check your local carry laws before making any multitool with a locking blade your everyday carry.
