The tools are metal but the tyre levers are plastic and too short for my liking so I carry a seperate pair, the chain tool uses one of the allen keys to operate it so there is no need for a seperate handle thereby saving space/weight.
I prefer this to a multitool and the tools are actually usable unlike some toolkits I have used it when I service the bike.
I can fit this toolkit, 2 x innertubes, patches, cycle coil lock, 2 x large tyre levers, roll of PVC tape, latex gloves, tie wraps, wire cutters and spare gear/brake cable in one of these ->
