This paper presents the results of preliminary experiments that were carried out with the Rock Strength Device (RSD), to investigate the feasibility of determining rock strength parameters from cutting tests. The approach used to determine the strength parameters of the rocks with the RSD is novel. It is based on an interpretation of the forces required to "scratch" a rock. This approach has many advantages over the conventional method for measuring strength parameters: Low cost and portability of the RSD, operational simplicity and rapidity of measurement, ability to make many measurements, ability to provide a log of strength from cores, and relatively non-destructive testing of the rock core.
