There's a lot to like about this diminutive multi-tool, which offers a useful collection of tools in a small package, but we worry that the separable Torx head won't last long.
The RavX Agent X packs a lot into its 109g: tyre lever; flat and cross-head screwdrivers; 2, 2.5, 3, 4, 5, 6 and 8mm Allen keys and a Torx head. The quality of the tool heads is decent and the whole thing packs down nice and small. You won't have trouble finding space for it, though you might have trouble actually finding it!
The tyre lever is supported by the tool body to brace it in use, but the other tools are able to move freely. That makes them slightly fiddly to use, but that's a criticism of most multi-tools. Otherwise, as a tool kit to fix & adjust things out on the road or trail, it works.
Our only major complaint is that the Torx head is stored inside the tyre lever as a separate bit; you slip it on the 4mm Allen key to use it. Experience of similar designs suggests that sooner or later separate bits become separated forever. We'd rather see them permanently attached.
