Description
Box-cutter keychain
I've created this box cutter that is made to fit in your keychain.
The knife uses blades from an exacto knife. All the parts fit one build plate.
The knife has a spring mechanisn that means it locks in either drawn or withdrawn position
Assembly is straight forward - in the tip there is a dovetail that slides in place, and in the back the cap has threads making it easy to change blades.
See gif for assembly. Note that the knifes position in the “sled” is important to orient correct.
I recommend a bit of lubrication inside the knife for ease of use.
