What is the best multi-tool on the market? The answer is very simple. It is the multi-tool which you keep with you (in the same way as a Smart Phone is often the best camera, simply as you always have it with you). Fortunately these days there are a lot of clever people dedicating hours of design and testing to creating multi-tools that fit in with your life and the items you carry every day. The credit card multi-tool and key ring multi-tool are two such developments. As they are always with you, perhaps they really are the best multi-tool to have - and they would come in handy on one of our expeditions.
