In field hockey, each player carries a stick and cannot take part in the game without it. The stick for an adult is usually in the range 89–95 cm (35–38 in) long. A maximum length of 105 cm (41") was stipulated from 2016. The maximum permitted weight is 737 grams. The majority of players use a stick in the range 19 oz to 22 oz (538 g - 623 g). Traditionally hockey sticks were made of hickory, ash or mulberry wood with the head of the sticks being hand carved and therefore required skilled craftsmen to produce. Sticks made of wood continue to be made but the higher grade sticks are now manufactured from composite materials which were first permitted after 1992. These sticks usually contain a combination of fibreglass, aramid fiber and carbon fibre in varying proportions according to the characteristics (flexibility; stiffness; resistance to impact and abrasion) required.
