It is proposed to evaluate the effectiveness of the tool penetrating by the medium resistance to this action - the lower the resistance, the more effective the tool. The medium resistance can be determined by using rigid-type loading devices, when the immersion rate of the tool is monitored at steady loading speed. Another method is shock loading with measuring the penetration depth and the time to reach the depth. The paper provides a solution to the problem in dynamic setting that is the medium resistance to deformation is set at a given tool mass, its initial speed of immersion, known values of penetration depth and time. Comparing the resistance of the medium for differently sharpened tools, the one that delivers the minimum resistance of the medium at penetration to a given depth is selected.
