The sharpening angle is between 30° to 35°. This is the angle that gives you a sharp cutting edge, so it's the one you must maintain by 'honing' the chisel regularly on an oilstone. If you're cutting softwood or doing very delicate work, keep the angle closer to 30°, because that will give you a sharper blade
