In order to move heavy tree trunks after felling requires not only a lot of strength, but also the right tool. The Sapie has been an integral part of domestic forestry for hundreds of years and is part of the basic equipment of every forester.
EXPLANATION OF THE PROBLEM
After consultation with some foresters and forest owners, two main problems with the use of the Sapie crystallized. The handle, which in most cases is made of ash wood, breaks very easily due to leverage forces. Second problem is the unergonomic lifting motion witch was also criticized.

CONCEPT
The tip is forged from C45 carbon steel. One side is designed to penetrate wood and is equipped with three notches to minimize slipping. The other side functions as a hammer.
Tip is inserted in the steel and glued together.

The handle is made of glass fiber reinforced polyamide (short GFK) and shaped more economic. The handle is egg-shaped to provide maximum stability and resistance. The coloring of the handle provides the possibility of making simple measurements. The first mark is at exactly 33cm from the beginning of the handle (firewood length), and the second mark is exactly at 100cm (meter pieces).
In the rear part of the handle a “carrying bolt” is inserted, this is used for carrying heavy unwieldy pieces of wood.
The rear of the handle is a wedge, also forged from C45 carbon steel, for splitting wood and additionally it serves as a slip guard. The purpose of the hole is for hanging the tool on a wall when it is not being used.
END
By redesigning the Sapie, I am not only trying to simplify the act of manually moving lumber, but also to create unique selling points by using new materials and shapes.
