I love cricket, I've been playing the sport for a longtime now. I played for my province and then played at the national level but then I had to quit because of a back injury. I will regret quitting all my life but then it wasn't really in my hands. But since i still love it as a sport but can't really contribute to it as a sportsman I want to contribute to the sport as an engineer. Well people might think whats so great about the design of a cricket bat its just a wooden piece, but its not that easy there are a lot of things that go into it. There a large number of factories all around the world making bats.
The
blade of a cricket bat is a wooden block that is generally flat on the stiking face and with a ridge on the reverse (back) which concentrates wood in the middle where the ball is generally hit. The blade is connected to a long cylindrical
cane handle, similar to that of a
tennis racquet, by means of a
splice. The edges of the blade closest to the handle are known as the
shoulders of the bat, and the bottom of the blade is known as the
toe of the bat.
The bat is traditionally made from
willow wood, specifically from a variety of
White Willow called Cricket Bat Willow, (
Salix alba var.
caerulea), treated with raw (unboiled)
linseed oil. The oil has a protective function. 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 current design of a cane handle spliced into a willow blade was the invention in the 1880s of Charles Richardson, a pupil of
Brunel and the chief engineer of the
Severn railway tunnel.

Law 6 of the
Laws of Cricket,
[2] as the rules of the game are known, limit the size of the bat to 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. Appendix E of the Laws of Cricket set out more precise specifications.
[3] Modern bats are usually machine made, however a few specialists (6 in England and 2 in Australia) still make hand-made bats, mostly for professional players. The art of hand-making cricket bats is known as
podshaving.
Also technology has influenced the manufactoring of bats in a great way. The hand-making process is no longer used. Only when a cricket bat is made on special request one by one of the greats of the game, then podshaving is probably used. But I'm not quite sure.
Australian cricketer
Dennis Lillee briefly used an
aluminium metal bat in 1979. After some discussion with the umpires, and after complaints by the English team that it was damaging the ball, he was urged by the Australian captain
Greg Chappell to revert to a wooden bat.
[5] The rules of cricket were shortly thereafter amended, stating that the blade of a bat must be made solely of wood.
[2]
tenzin and
Puma have created bats with lightweight carbon handles so that more weight can be used for the blade. In 2008, Gray-Nicolls trialed a double-sided bat.

In 2005,
Kookaburra released a new type of bat that a
Carbon fiber-reinforced polymer support down the spine of the bat. It was put on the bat to provide more support to the spine and blade of the bat, thus prolonging the life of the bat. The first player to use this new bat in international cricket was Australian
Ricky Ponting. However this new innovation in cricketing technology was controversially banned by the
ICC [7] as they were advised by the
MCC that it unfairly gave more power in the shot and was unfair in competition as not all players had access to this new technology. But this was not taken lightly by Australian media as Ponting had scored plenty of runs since he started to use his new bat and English reporters blamed this on his new, 'unfair' piece of technology in his bat.
At
IPL 2010 a new bat manufacturing company called Mongoose announced new design of cricket bat known as
Mini Mongoose. The bat has a shorter thicker blade and an longer handle with the splice set in the handle to provide more hitting area in the bat face, to play huge shots. This is as the unique low centre of gravity gives the bat much greater bat speed and as it has a shorter blade the blade can be thicker for the same weight meaning there is more bat behind the ball allowing the ball to be hit further. This bat is in use by
Andrew Symonds,
Matthew Hayden,
Stuart Law,
Praneet Singh and
Dwayne Smith. However it does have several drawbacks as it is shorter it is less useful for defensive batting and doesn't offer the same protection to a short ball. This means it helps the attacking game but at the expense of the defensive game. This restricts its usefulness to Twenty20 where attack is the aim rather than Test or championship cricket where longer innings require a more subtle approach.

So after all its not just a wooden piece a lot of work goes into this and looking at the rise of T20 cricket and its entry into the olympics(http://www.espncricinfo.com/ci/content/story/447930.html) looks like this industry has a very bright future. I would definitely look to work for this industry in the future.
