Mult-lock garrison magic key
I made myself what is in principle a bump key, however i shaved off the one edge to allow the use of a tension wrench
Its basically a rake key for dimple locks. Rake keys in normal pin tumblers are crap, however works a treat on mult-locks
very easy to make get yourself a blank and drill your cuts carefully with 1/8 drill bit. Then repeat with larger drills to remove excess material. You need to make sure you arent left with any ruts in which a pin could be trapped when inserted, pins should ride smoothly over the key
