Although we’re Web guys at heart, there’s something to be said for a quality pen. And when that pen is crafted from chromium plated brass and includes a caliper ruler, standard ruler, thread scale and tire tread gauge, all the better. The German-made Cleo Skribent Messograf Caliper Pen ($28) combines form and function for a multi-purpose writing tool that’s a favorite among engineers and architects.

Leave it to the Germans to incorporate useful features into an everyday item. Sure, not everyone’s job requires the use of a Vernier caliper ruler, but it’s nice to know you have one in a pinch. For those more concerned with writing than MacGyvering, the retractable ballpoint pen includes a replacement ink cartridge. Check out a few more photos after the break.
