I can't recall whether it was Bart, Bruno, or maybe another member from Belgium, but someone posted photos of roads paved with BBW, fences built out of the stuff, IIRC a home with a BBW rock face on the exterior, and last but not least, a large table made of BBW. Whether it was Bart I don't know, but the fact that up until the past decade or so, BBW was not even considered as a material viable for honing.
