Hey Dave,
Thanks for writing. I find that I’m ready to re-paste after 100 knives or so. We often go to shows and don’t re-paste for the entire show. If the strops don’t seem to be be performing anymore, I apply a little more. A little goes a very long way. For cleaning, you can scraped them off with a razor blade. I’ve heard of people sanding them, but haven’t tested that yet. I’ll post results once I’ve had a chance to check it out. I’d love to see some of your results if you get a chance to take photos.
