Multi tools that are genuinely capable of fettling the entire fleet are as rare as rocking horse droppings. Cue the Tern Tool. Originally conceived for the brand's own range of bikes, it's comprehensive enough for road, tourer, mountain bike, tandem - the list goes on.
A neoprene carry sack serves two functions - most obviously protecting the rider from puncture wounds in a spill, but also giving additional comfort when using the tool.
Let's get the price out of the way early on, as you might well be baulking. It's at the absolute upper limit of what I'd pay for a multi tool, but it's good enough that I would pay it.
Measuring 75x40/10mm, its slimline double decker profile lacks obvious machismo, but quality of construction is excellent.
The frame this looks resin but is in fact coated steel for rigidity. A beefy chain tool chomps through 7/8/9 speeds for breakfast and track types for lunch while two nickel plated wrenches stow away beneath the base, connecting securely via two stubby Allen keys.
Focusing on the bed of Allen keys, Tern has optimised space by tapering the larger 4, 6, torx and Philips functions so flat, 2, 2.5 and 3mm sections shelter inside. This doesn't present much of a compromise either, since those sorts of fixings belong to brake pivots and similarly low stress applications.
Bottom line - they all fit snugly and even stubborn stem/seat bolts submit without much fuss , due to the leverage the tough frame provides.
So then, to those sensibly configured wrenches - these fit inside two corresponding cut outs and needed cajoling free with an engineer's mallet to begin with. Both wrenches are designed to be flipped and refitted.
A well-machined 15mm end made short work of stubborn track nuts - pedals too, although it's too beefy for adjusting hub cones. Likewise the 10mm sibling is perfectly situated for administering TLC to old school cantilever/centre pull hardware. The eight glue-less patches and sculpted tyre lever are novel get out of jail cards but not ones I'd be comfortable using too regularly since the latter's steel.
One of the best-designed and comprehensive multi tools I've used in ages.

Nickle plated high tensile tooling.
Performs most tasks exceptionally well.
Tool materials seem very rugged and should last a very long time with basic care.
Offers surprising amounts of torque wihout digging painfully into the palms, or feeling remotely whippy.
Good value in the sense it is very well made but pretty much my limit for a pocket tool nonetheless.
Tell us how the product performed overall when used for its designed purpose
The tern is a very unique design which could prove that one tool can fettle an entire fleet. Obviously there's an element of compromise-some might bemoan a disc brake pad spreader but nothing I couldn't live with.
