The Passport Micro doesn't have an 8mm Allen key, so it's not duking it out with the bigger boys in this test. But it is well made and surprisingly solid for the price. We're loving that bottle opener on the side, too.
The teeny-tiny size might challenge those with large hands, especially when they've got freezing fingers. At £6.99, though, you almost can't afford not to stuff it into your jeans pocket, backpack or glove compartment 'just in case'. After all, you never know when you might need to open a beer.
