The Cinch

 Ok this one is a gag gift, we admit it. Its a great way to mess with mathematicians. Please don’t give this to children that would just be irresponsible.

Why: This world is being torn apart by far too many things. Why should we let something like measuring separate us? For too long, the war between metric and imperial has ruined lives and separated families. We have the solution. “The Cinch” is half way between an inch and a centimeter. “Through compromise we can all get along.”

How to build one yourself

  • Laser cut this file

  • Spread the word of the cinch

What: A ruler that measures things in Cinches. Each ruler is 11 cinches long, half way between the metric 10 and imperial 12. Also, for your convenience, each Cinch is divided into 9 equal units.
