It's a material called "shred carbon fiber". This particular sheet had silver dust infused into it.
It's beauty is unparalleled, it has to be seen to really appreciate it. This scale was made by BellaBlades, a member here on the forum. He does great work, he's a great guy to work with too.
It's small "shreds" of carbon fiber and silver set into a resin matrix. There's some with copper or gold too, and others with colored resin like red and blue. You can actually shine light through it in certain spots! Pretty rare stuff. Not sure, but I think only one place makes it (the same guys who make C-tek).
I love it! As far as grip goes, its no different that standard CF imo. It's no slicker that the Ti side of my 0562.
