Hi Harvey et al,

There's lots of different knurling tools with lots of different patterns for different applications. The pattern on my Weinmann/Schwinn rims is similar to some of the tools around my company's machine shop. And I can see how they could set the knurling tools to do rim sidewalls. I don't think it's a stamped surface.
