I don't know why I hadn't memorialized this tool earlier than I did (March '07). I'm sure Norm's used it before (he has—see below), but it really stuck out for me in this episode (upon reviewing it three years later) because he spent some time demonstrating one effective use in the construction of the project (1601—Butterfly Table). I can't imagine a workshop without one, it's that useful a tool.
Appearances: Episodes 201, 206, 1601
