Abstract

The present invention relates to an improved type of gas-powered cutting tool of the general type whose tool section with its cutting blade (24) operates against a bucker (2a) that consitutes a fixed part of a body (1) in which a piston-cylinder arrangement for powering the cutting blade (24) of the tool against the bucker (2a) is integrated. The present invention more exactly constitutes a re-design of previous cutting tool designs that when implemented means that such cutting tools in the future will better withstand the overloads caused by being fired when empty or when the quantity of material to be cut is significantly less than that for which the cutting tool was designed. The distinguishing feature of the present invention is that the rear piston (12) which powers the cutting blade (24) has been provided with an internal damper (16) that prevents the cutting tool from becoming overloaded.
