Chuck out that cumbersome spanner set, the Craftsman Figure Eight Wrench has got you covered. A fast change tool, adjustable to eight differing sizes, it'll make light work of 6pt, 12pt, 4pt, spline, external torx and even old hex fasteners that have become rounded. Only weighs one and half pounds but is ultra-tough and even if you do somehow manage to break the thing, fear not for it comes with a lifetime warranty.
