Abstract
A shock absorbing system has a nose assembly that is formed to inwardly collapse on impact and is guided by a sleeve that can slide with the nose as the nose collapses or can extend for a portion of the length of the nose while being held fixed. In the latter instance the nose can have a leading end that has a biasing member in a resilient material so that on impact some of the shock is taken up by compression of the biasing member with subsequent extension of the biasing member retracting the resilient covering so that it is less likely to bind in the surrounding tubular. The leading end of the sleeve or the resilient material encasing the biasing member also soften the blow to a closed ball when the tool is dropped so that the ball surface is less likely to mar.
