Just seen this. The Edge Black 100% Domestic Wool Heavy Cut Pad - Auto Geek Online Auto Detailing Forum
I believe they have been around for a while, they cut pretty well but don't finish down that great. Check out this thread from 2008, they mention black edge wool pads in there. Pay attention to Asphalt Rocket's post at the bottom of page one. http://www.detailingbliss.com/forum/f37/micro-surface-tuf-buff-black-wool-6200.html
