What is a kickback in woodworking and how can it be prevented?

A kickback in woodworking is when a piece of wood is forcefully ejected back towards the operator of a power tool, such as a table saw, during cutting. This can be dangerous and cause injury. To prevent kickback, always use proper safety equipment, maintain tools in good condition, use a riving knife or splitter on the saw, and avoid cutting warped or twisted wood.
