Four Keyed Safe?
Ok, so in a book I recently read, the plot of the story was to find the keys to a safe the boys father had left him for his 13th birthday. This safe had four keyholes with four matching keys, so I want to replicate this safe. Any ideas on how to create blueprints for it. Remember, the safe had four keys on the outside, it's not like one safe, then another, then another.
Anything would be helpful.
