After cutting, the new key is deburred: scrubbed with a metal brush to remove burrs, small pieces of metal remaining on the key, which, were they not removed, would be dangerously sharp and, further, foul locks. Different key cutting machines are more or less automated, use different milling or grinding equipment, and follow the design of early 20th century key duplicators.
