Lock Buster: Yale

thingiverse

This is a model for a Lockbuster key that works with Yale-style keyways. A Lockbuster is a key designed to instantly render a lock useless in any situation. To use this key, simply shove it into a Yale-style keyway. The unique cuts on the blank ensure that the key cannot be pulled back out once inserted or hammered through in an attempt to remove it. Instead, the key is designed to shear off cleanly at the right spot.
