Just posted about this, but I literally have a couple shaves under my belt, from 20some years ago. I'd love to get it cleaned up and try using it again.
Obiwan may still be following this thread, but I bet if you send him a private message, he can help you out. David is one of the nicest guys you'll meet on B&B. Good luck with your razor and round 2.
Anywhere from $0 - $20, from what I've seen, assuming there's no chips or other damage. Frequency depends on a lot of factors. Your technique shaving, stropping, the edge itself, etc. Doc226, who appears below, had a razor going for about 135 shaves, just stropping, before his razor needed to be re-honed. Many people have at least two razors, so that when one needs to be honed, the second may be used to shave. Some of us even have more than two . . . .
