While this Chairmaker's Scraper was designed primarily for chairmakers' use, it can be used for any other scraping task in the workshop. The appeal of this tool is that it can be used as is for scraping flat surfaces with the included straight blade. For scraping round pieces, additional blades are available: three concave shapes in 12.7mm(1/2"), 22mm(7/8") and 31mm(1.1/4") diameters and one convex 38mm(1.1/2" radius). The straight blade could also be ground to a specific shape. All blades are made from 1.5mm(0.060") thick high-carbon steel. The machined cast steel body is fitted with a large rear handle and a front knob of African rosewood
