ABSTRACT:
An ice chopper having a blade for initially engaging ice with a small force followed by an impact of a larger force to break up the ice. The ice chopper has a tube for a handle having a second tube inside with a compression spring. The second tube has a blade attached, which engages ice and pushes the second tube up inside the tube simultaneously compressing the compression spring. When a stop is reached the second tube stops retracting and the impact force of the downward movement of the tube is absorbed by the blade for breaking the ice. The ice chopper is then lifted off the ice, the compression spring pushes the second tube and the blade downward and the ice chopper is ready for another stroke. An ergonomic handgrip is attached at the top of the tube for gripping the ice chopper.
