Sweet letter opener set!
The original design by Archermtl was very appealing and well designed. I just wanted something with a little more of a "tactical" vibe for those insidious amazon boxes! I made them so they could be printed in halves or used solo.
I only intend them to be used on boxes so I have not strength tested them on anything other than cardboard and paper and can only recommend you do the same. But just in case they are too pokey, there is a blunted trainer version you can print in TPU to keep yourself safe.
I may design a sheath at some point.

Taxation is theft. The politicians are supposed to be YOUR servants.
