Kennedy inside the hollow die cast aluminium hammer head are thousands of steel pellets which impact a split second after the hammer face, reducing rebound whilst also adding to the force of the blow. Each hammer has two replaceable screw-in nylon hammer faces that can be easily replaced when they become worn, without the use of any other tools - minimising down time.

The striking faces are reinforced for extra strength and to prevent fracturing from off centre strikes. The nylon hammer faces have a precision moulded screw thread that screws securely into the single piece die cast aluminium hammer head, the handle is a high strength girder section that has a shock absorbing soft dual material grip, for improved grip and control.
