sticks. Mi'kmaq continued to make hockey sticks until the 1930s. Hockey sticks were mostly made from the maple or willow trees, which was also a common choice for golf club shafts and wooden tools. However, as hornbeam supplies diminished, it became more cost effective to use other hardwoods, such as yellow birch and ash. Ash gradually became the preferred medium, and by the 1920s an ash hockey stick crafted from a single piece of wood was the type most commonly used. These early sticks were extremely heavy and not very forgiving, although they were extremely durable (Hall of Famer Moose Johnson famously used the same extra-long stick, which gave him a reach, his entire career). There were only a handful of major developments in hockey stick technology between the 1920s and the 2000s. Foremost among these was creation of the laminated stick in the 1940s, where layers of wood were glued together and sandwiched to create a more flexible and durable design. In the 1960s, companies began adding another lamination of fiberglass or other such synthetic compound as a coating, which further added to the durability and usability of the stick. Also in the 1960s, players began curving the blade of the stick, which dramatically changed the physics affecting players' shots. In the 1970s, cricket and baseball bat manufacturers began experimenting with lightweight steel alloys as a replacement for the traditional willow or ash bat. Hockey stick designers followed suit in the early 1980s, introducing first a single piece all-aluminum stick. This design was not popular, as the stiff aluminum did not have the proper "feel", and so a design featuring an aluminum shaft and a removable, replaceable wooden blade was tried. This became very popular in the late 1980s and early 1990s, challenging the prevalence of the traditional wooden stick for the first time. In recent years, the aluminum stick, as well as its wooden counterpart, have largely been replaced by more advanced composite designs. Common building materials include fiberglass and carbon fiber. Composite sticks generally weigh less than their aluminum forebears, and they can be manufactured with more consistent (and varied) physical properties than their wooden counterparts. They are, however, considerably more expensive than wooden sticks, and are not as durable as the older aluminum sticks. Materials Over the last two decades, there have been tremendous advances in the material technology used to create hockey sticks. The vast
