Dear Father Steve: I spent over an hour searching, and was finding only places about "coping" with emotional problems, until I had the inspiration to search for "capentry coping" and up jumped a site by Bob Vila, of "This Old House" fame, and lo and behold, he has a site about the coping saw. Hallelujah!
