ABOUT OUR CUTAWAYS: Starting with a working padlock, the lock is carefully disassembled and the case milled to reveal internal working parts. Depending upon the lock, the face, back and sides of the case and shackle, and internal visible parts are carefully polished and the padlock is reassembled and tested (the lock as pictured is the lock you will receive). Each cutaway is a one-of-a-kind gem, created by an expert locksmith and collector (Randy Oxley). These cutaways are hand-made in very limited numbers, so if you are interested please don't wait to bid. The quality and performance as a collector's cutaway are guaranteed! - eBay (30 Nov 2012)
