Chair devils are wonderful tools for final shaping and smoothing of round parts such as chair spindles and posts. The specially shaped scraper blade rounds the workpiece, removing any spokeshave marks. The machined steel bodies are fitted with hardwood handles shaped for comfort and control. The machined toe and the two thumbscrews are solid brass. The high-carbon steel blades are 1mm(0.040") thick, hardened to HRC 48-52, and come with a finely ground 45° cutting edge. 22mm(7/8") diameter for rungs. Full instructions included. These tools are a joy to use and are an excellent companion for spokeshave use.
