This device mechanically replicates the impact of a ball striking a cricket bat’s surface. It simulates the repetitive striking action required to “knock-in” a new bat, preparing the willow for match conditions by compressing its fibers and reducing the risk of cracking upon impact with a cricket ball. The process traditionally involves manually striking the bat face repeatedly with a mallet or a specialized hammer. A typical automated device holds the bat securely and uses a rotating wheel or arm fitted with impactors to deliver consistent blows to the bat face. Some advanced models offer adjustable speed and impact settings to tailor the knocking-in process to different bat types and player preferences.
Automated preparation offers significant advantages over traditional hand-knocking. It provides a consistent and controlled knocking-in process, minimizing the risk of human error and ensuring uniform compression across the bat face. This uniformity leads to improved performance and durability. Moreover, automation significantly reduces the time required for bat preparation, allowing players and bat makers to save valuable time and effort. The historical development of these automated methods reflects a growing appreciation for scientific principles in bat preparation, moving beyond traditional, often anecdotal, methods.
