Enjoy this reimagined doorstop to make it look like you are using a knife to hold it open.  The knife is inspired by the knife used in the Rambo movies and the blade has three sizes: A full size, a ⅔ size door stop, and a ⅓ size door stop.  The knife is mounted at 80 degrees.  I would love to have some feedback on real world use to improve the design, so please rate/comment!
