I'm using one of these Kryptonite combo cables:



and while it has never been cut, and has not required much maintenance (graphite to help the dials spin), after X years (5?) pretty much all of the numbers have worn off. It has dots for the zeros and squares for all the others, so I count up or down by feel but I don't know which way is which (if each click is moving closer to or farther from the zero). But if it doesn't work the first time, I rezero, count back the other way and do it again.
