For fine shavings when working on flat and long curved surfaces such as bows, boats, slats, planks and edges. Because they are guided by hand and are sensitive to the wood structure, spokeshaves must have hefty bodies and thick cutting blades (3.2 mm). The blade can be adjusted with knurled screws, the mouth opening with supplied shims. The radius of the round version is 44 mm, while the concave version has an inside radius of 33 mm.
