The proper sharpening of the tools used by the wood turner is a key part of the success of his work. For sharpening, the wood turner more frequently uses a grinding wheel, better suited to his activity, than an oil stone. In terms of cutting edge, his tools do not encounter the same problems as those of the sculptor or cabinetmaker. They are confronted with the heat produced by the friction against the wood which quickly dulls their cutting edge and with bad handling which can make them unusable. The frequency of sharpening must therefore be high, even during shaping : a turning tool which cuts a piece of wood rotating at a speed of 2000 revolutions per minute can perform in one hour as much work as a carving tool or a wood chisel in several months.
