Anodizing does produce a very hard surface, namely of aluminum oxide. This is the same compound that is used to make grinding wheels. The problem is that this hard surface is very, very thin. The metal underneath is still ordinary aluminum, which even in the best of cases is a very soft metal.

I had been under the impression that the reversing wheels were “hard-anodized” for durability. I suppose the right anodization technique could offer the best of both improved hardness and decreased friction, though, so both traits may very well be correct.

The red reversing wheel is made from an anodized aluminum, much like some of the high tech cooking pans today. It provides for a very slippery surface.

At first glance, I thought that was normal:P Though…. rolexes have aluminum parts?!

That must have been a pretty mess to clean up after. I can’t say I’ve ever seen a reverser cut that uniformly before.
