Husqvarna's Superlok GM Slabbing blade does one thing and one thing only. It cuts through your glass like a hot knife through butter. 

It isn't pretty, but it's effective. If you need to remove chunks of glass from your pieces quickly and efficiently, then the Superlok GM slabbing blade is for you. This blade will leave quite a bit of edge chipping, but it will cut your glass faster than anything else we have.
