Whether you are a designer, an architect, an engineer, or simply enrolled in an art class, you know you need at least these basic tools for sketching—pencil and ruler. But just like the plight of our good buddy The Pen, these two are prone to disappearance whenever we need them most.
Rule/One changes all that by creating a compact design that combines both the pencil and the ruler into one package–the Rule/One Writing Tool. This 2015 Red Dot Design Awardee has interchangeable heads so you can write both on paper and tablet. It is also compact that it fits any folder, pocket, and book as a bookmark.
It may not be a tactical pen alright, but it still rules (pun intended). To avoid being listed as MIA, carry it on a lanyard then detach when needed.
