Double row pinstrip breaker

This is a tool for breaking those snap apart pin strips that are used for ribbon cables and such on the CORRECT score line. If you have ever tried to break these pin strips by hand without a tool like this, you know how difficult it can be to aim and get them to break on the line that you intended to break them on. This tool makes it easy.

How to use:
Print two copies. Slide both of them onto a double row pin strip with the curved sides facing each other like the picture above. Line up the gap between the breakers with the spot on the pin strip where you want to break it and then roll the breakers against each other to snap the pin strip.
