Excellent (and overdue) topic, Mark.
I just turned over 100,000 miles on my vehicle. While new car statistics may seem interesting, comparable statistics over 25 or 50,000 mile periods are really more useful.
I took a hand cut dovetailing class years ago. Halfway through the practice project, I could feel the chisel edge dulling on my O1 chisel. The instructor's Japanese steel chisel was still going strong.
Pavol Sandor has done several you tubes with an innovative rope cutting tester of his own design. Even with no understanding of Slovak, his message is clear through the visual part. You can see the results of the knife edge dulling. I highly recommend watching Pavol's you tubes. His testing procedure is very practical. His you tubes tend to be lengthy. Do not stop part way through and figure you have absorbed the jist of it. Absorb the entire you tube. See the whole picture, not just a partial snapshot.
