A hand operated crimping tool with at least three crimping dies, the crimping surfaces of which together enclose a crimp opening arranged to receive a workpiece to be crimped. The crimping dies have movable pivot points that move when the handles of the tool are moved relative to each other. Each of the crimping dies is arranged between two guide elements on the body of the crimping tool and further has a respective cam surface and a respective stop surface, the respective cam surface being arranged to cooperate with a guide surface on one of the guide elements and the respective stop surface being arranged to cooperate with a guide surface on the other one of the guide elements, thus guiding the movement of the respective crimping die when the pivot points for the crimping dies are moved relative to the body of the crimping tool.
