This site offers a fairly extensive list of user and collector-grade woodworking and machinist's hand tools. For the last ten, the owner has haunted flea markets and auctions, buying far more tools than can be used. Her collector instincts are directed to finding hand saws with local (southeastern Massachusetts) hardware store marks, and 19th century patented American braces.
