Given the bewildering array of mutant multi tools, it's rather nice to get back to basics.
Comprising four common sizes of Allen key (3, 4, 5, 6mm), nylon tyre levers, patch kit, small adjustable wrench and flat screwdriver, the whole bundle is held in a small pouch which keeps everything compact (particularly if, like me you are prone to losing Allen keys or discovering at that crucial moment you've left home without the patch kit!).
As would be expected the tools are well made and should, with care, last many years.
Individual Allen keys score over pen-knife style multi tools by offering greater leverage and dexterity in certain situations such as mounting bottle cages on small frames, although I would've preferred to see a 1mm size and a Phillips head screwdriver.
The mini adjustable wrench will do most little jobs - great for nipping tight a rogue mudguard stay bolt or similar fitting while out on the road but it's too small to fit 15mm track nuts, requiring a further spanner which is a little disappointing if you like to travel light.
