Hmm Rule/One ruler marries the rigid with the write

Designers, architects and construction workers all need three essential things to do their jobs: a pen, paper and ruler. Hmm Rule/One combines two of these things in one. This compact aluminum 13cm long ruler comes with a built-in pen. The ruler fits well inside of any notebook or comes with an attachment that makes it easy to wear around. One of these two-in-one tools goes for a somewhat imposing $45 donation with an estimated delivery date of July 2014. Higher reward tiers come with different choices of color. Hmm Rule/One hopes to raise $20,000 in its 43-day run on Kickstarter.
