Hand-operated striking tool enabling vibrations to be reduced, and method for manufacturing

A method for manufacturing a hammer-type, hand-operated striking tool, the method comprising:

• providing the tool comprising:
• a gripping handle;
• a striking head;
• an intermediate shaft extending through the handle and supporting the head;
• and
• an intermediate link part,
• the handle comprising a tube in which the shaft partially extends, the shaft and the tube being respectively made from first and second rigid materials each presenting a hardness within a first hardness range,
• the shaft having a radial area that bears against the tube via the link part, the link part being positioned between the tube and the shaft and being made from a flexible material presenting a second hardness lower than the first hardness range so as to absorb vibrations,
• the shaft having a free terminal area that is not covered by the link part, that spans from the link part to a terminal end of the shaft, and that is radially separated from the tube so as to be able to vibrate freely in an internal volume of the tube, and
• the tool being configured so that an air volume fills the entire space between the free terminal area and the tube, and the method comprising the steps of:
• mutually securing the head and the shaft;
• fitting the link part in place on the shaft in the final position that the link part and the shaft are to take;
• and
• engaging the shaft and the link part inside the tube.
