The Sawblade EP (also called the Buzzsaw EP) is a handmade CD-R made by Isis for their tour with Neurosis and Candiria, limited to 200 copies (the first 40 with red blade inserts, the remaining 160 with black). It was sold at these shows at a limit of 15 per night, and the leftover copies were given to friends of the band as a year-end "thank you" gift. The vinyl run of this release was limited to 250 copies. As such, Aaron Turner doesn't consider this an 'official' Isis release, describing it as “more like a special artifact for us and the few converts we had at the time”.
