The Sawtooth Grin is a mathcore band that formed in 1999 in Montrose, New York. They went through several line-up changes before disbanding in late 2004. Their first EP, "Cuddlemonster", was released on the label Dead By 1918. A second EP called "Pervavor" was written and recorded in 2004. It featured a new guitarist, Will Joel, and a sound change from grindish mathcore toward death metal, but didn't see an official release until 2011.
