The Victorinox SwissTool Spirit X Swiss Army multi-tool is a smaller and more stylish variant of the regular SwissTool. It is slightly curved, which makes it easier to use, and very satisfying to hold in your hand. If the regular SwissTool is the Volvo of the multitool world, then the SwissTool Spirit X is the Ferrari! The X version is similar to the regular SwissTool Spirit, but it has a plain blade instead of a serrated one.
