A chemical etching technique might work, but I have no experience.  If you
want to pursue, check with proceedings of the Electrochemical Society or a
plating magazine.  Good luck.

Subject: forming feather edges / burrs in metals


>I am trying to form, good quality, homogeneous feather edges (or burrs) on
