Buck X-Tract multitool: one hand only
Buck is a well known knives manufacturer. They used to sell a multitool: the BuckTool. This model never did as well as the Leatherman and Gerber tools. Now, they are trying again with the X-Tract. This is a radically different multitool. It features only the basic tools: a pair of pliers, a knife, a normal and phillips screwdriver and (curiously) a can opener. The unique selling point is the fact that all the tools can be opened with one hand. I am sure most outdoor fans will instantly see how useful this is.
