chisels
They are made of trapezoidal steel bars. The tip is sharpened with precise angles and must always be very sharp. During use you must be careful not to run into knots, and metal parts that could break them irreparably.
To use them correctly, place them on the wood at an angle of 30 ° and remove little material at a time. Never point the cutting edge towards the body during use, to avoid accidents.
The blade of the scapelli must have a precise inclination according to the hardness of the wood (from 25% to 35 ° degrees).
To sharpen them correctly, use the stone resting them on a wooden wedge to maintain the correct inclination.
