Micro Utility Knife Keychain

This knife is an attempt at making the smallest, most functional utility knife holder keychain. Its an exercise in shrinking a form factor, maintaining a consistent aesthetic and taking advantage of 3D printing to make a final product.

I started from thing:3782051 and wanted to change some of the features. I was very pleased to find the .STP files which made remixing much easier. Primary changes are the location and contact point of the spring, a way to slide the blade out more securely, and how the detent is designed.

You can get away with just printing the holder, but the blade is a little too slippery for my tastes.
