Part multi-tool, part writing instrument, all German engineering. the Cleo Skribent Messograf pen ($23) works great as a writing tool, accepting any Parker-style ballpoint or gel refills. But the chromium-plated brass body also serves as a metric screw thread scale, a tire tread depth scale, and as a 4-inch caliper that measures in both metric and inches. And not to worry, nervous pen-fiddlers — it still uses a standard click-to-open mechanism. [Scouted by Andrew]

You might drive a Prius, but that doesn’t mean you should be rolling down the road without the Trucker’s Friend ($50). This all-purpose, all-in-one tool incorporates an axe, spanner, hammer, nail puller, tire chain hook, pry bar, and lever into a single, rugged 21-inch body. Mesh hat and Big Gulp not included.
