The article deals with design of a coniform tool with rotary motion for splitting of logs. The tool is proposed using a fracture mechanics theory. The approach of energy balance during crack growth in a split wood log is applied for construction design of the shape of the splitting tool. The proposal of the tool shape is based on the experimental fracture methods. The only used criteria it is the demand of the minimum quantity of the consumed energy.

Keywords: fracture mechanics; wedge splitting test; fracture energy
