Plug readers: What would you do??

Any chance you have a pic of that plug before it ran in the engine?

Edited;
On their (Brisk’s) website the pic of that plug shows a very sharp electrode and ground strap. You are nibbling the edges off of everything and that is a sign of the very beginnings of detonation. Hopefully this isnt just a stock photo they use.

Is it possible the sharp edges are being removed by the wire wheel he is using to clean the plugs? He stated in this picture on page 1 that he used a wire wheel to clean the plug.
