Now here's a very odd name for a very handy tool. It sounds more like an obscure Swedish radio station or a high-power water pistol for long-range summer hi-jinx. But those clever fellows at Leatherman don't worry much about names. Their craft is all in the tool - and this is one very clever multi-tool indeed. Pay attention now, because size can be deceptive. At just under 6cm long - that's the length of your little finger - this is the first ultra-compact pliers multi-tool deserving of the Leatherman name. Inside its anodised aluminium outer sits a set of full-function spring-action pliers, three screwdrivers, wire cutters, a knife blade, the obligatory bottle opener and an awl tool. What's an awl tool? A tool for awl seasons. Obviously. It's even got a handy key-ring attachment so it can stay safely attached to your rucksack as you jump out of the C130 on the way in to Kandahar. Or maybe just Guildford. And don't let the choice of three colours fool you. If the choice was still metal, metal or metal, the P4 would still be a stunning piece of engineering. Only now you can choose a set of indestructible plier-based multi-tools to match your hiking boots. Which is a thoughtful touch.
