Clever, he's using a sawzall jig guide as his table to ensure a strait cut. Never thought to do that. He's still gotta use skill to prevent the cutting of the wood table. Cutting right in the middle there at the end is super cool, I've done that and seen it done but that is the cleanest cut I've ever seen done in that fashion. The jig could be used as a guide at that point since he was starting from the top but still a crispy clean cut
