* The blade - can be more or less curved outward, more curved out below than above, and even be sloped in relation to the shaft hole section [Pertersen 1919].<br>Side axes are characterized by being sharpened on only one side of their blade giving an asymmetrical cutting edge. This makes them able to cut at a low angle, achieving a smooth surface. [LEAHY 2003:p.17]
