Designer bezel

Hi,

I’m currently modifying one of my anvils so that I can forge
different sizes and patterns of bezel strip.

The question that I have about bezels, is this: would there be any
sense in having a .001 to .005 inch high rails on the side of the bezel
to help the cab stay in place? Or, is that overkill?

Thanks in advance for advice,
