Wenger's Evo Softgrip 17 from the ground-breaking Evolution series is a man's man's Swiss Army Knife to behold. Rather than restricting itself to nail filing, this gets thoroughly stuck-in to a whole host of manly challenges, including wire stripping, cutting, can opening. And tooth-picking.

These miniature marvels from Wenger, inventor of the original knife, not only put Switzerland on the map for something other than Toblerone, but have become global icons of smart design and beautiful, meticulous construction. The Evo 17 is a fine example of this tradition, with scope for no fewer than ten different implements in its ergonomic 3-inch frame. Stuck without a reamer or a caplifter (and aren't we all?). Then this little wonder can help. Need to open a can of beans but haven't got the wherewithal? Now you have.

What makes this model wondrous for the great outdoors is the sheer versatility of its functional range. From trimming to cutting, filing to cleaning, screwing to lifting, it's got the answer locked away neatly inside. All you need to do is carefully prise it open, and salvation is within your grasp, not to mention an honorary Generalship of the Swiss Army.
