Cricket bat
A cricket bat is used by the batsmen in the sport of cricket.
This specialised bat is shaped something like a paddle with a flat side and shallow V shaped side, the flat side is used to hit the ball. The bat is traditionally made from willow wood, specifically from the Cricket-bat Willow (Salix alba var. caerulea), treated with linseed oil. This wood is used as it is very tough and shock-resistant, not being significantly dented nor splintering on the impact of a cricket ball at high speed, while also being light in weight. It incorporates a wooden spring design where the handle meets the blade. The rules of the game limit the allowable size for a bat as not more than 38 in (965 mm) long and the blade may not be more than 4.25 in (108 mm) wide. Bats typically weigh from 2 lb 8 oz to 3 lb (1.1 to 1.4 kg) though there is no standard. The handle is usually covered with a rubber or cloth sleeve to enhance grip and the face of the bat may have a protective film.
Bats weren't always this shape. Before the 18th century bats tended to be shaped similarly to how hockey sticks are currently shaped. The game originally had lower stumps, the ball was bowled underarm (whereas now it is always bowled overarm), and batsmen did not wear protective pads, as they do nowadays. As the game changed, so it was found that a differently shaped bat was better. The bat which is generally recognised as the oldest cricket bat still in existance is dated 1729 and is on display in the Sandham Room at the Oval in London.
