Wafer tumbler locks are a type of pin tumbler lock that is used in a variety of applications. They are made up of a series of wafers that are stacked together to form a cylinder. Each wafer is slightly different in size and shape, and when the key is inserted into the lock, the wafers move in such a way that it allows the cylinder to turn and open the lock. These locks are often used on doors, cabinets, luggage, and other items where security is important.
