<p>The sleeve (1) contains a number of parallel spaced apart slits (12), each of which contains several raised tooth-shaped profiles (13), in between pyramid-shaped recesses (14) are formed. These recesses reduce the elasticity coefficient of the rubber material at the sleeve surface which is gripped by the tool user, so that the sleeve is rapidly deformable and can absorb energy from the tool, which causes the deformation to be slowly reversed.</p> |
