Abstract
The hockey stick comprises a shaft, a blade and a heel forming the connection between the blade and the shaft. It comprises a core having several parts (11, 12, 13), each part being made from synthetic foam having a different density to that of the other parts, based on different materials, in order to adapt the resistance and the characteristics of each part to the particular local stresses of the stick. The core is covered with three layers of woven materials (1, 2, 3).

- a shaft having a core of synthetic foam of a first density;
- a thin extended blade having a core material of a second density higher than the first density;
- and a heel forming the connection between the blade and the shaft and having a core of synthetic foam of a third density less than the second density, wherein the first, second and third densities are selected in order to adapt the resistance and the characteristics of the shaft, blade and heel to the particular local stresses of the hockey stick;
- and
