For woodworkers and other lovers of fine traditional woodworking tools, not much is more iconic than this Ebony and Brass Thumscrew Mortise Marking Gauge used by generations of English, American and Canadian craftsmen as they laid out joints and cut lines on boards and posts. Thumbscrew control to set precise mortise cut lines. With traditional scratch-awl pin markers. A first class traditional tool, not seen as often these days. Made in Asia now.
