The cutting ability of a blade is significantly impacted by the geometric characteristics of its serrations. This study will examine how titanium blades, with and without serrations, can cut into multiple types of materials. A total of five different blades and three different cutting block materials were used to examine the stresses, normal forces, and shear forces of the blade serrations. Analyzing the deformation of the cut material revealed how stresses caused by a serrated blade differ from those caused by non-serrated blades. The data from this examination was then used to determine the optimal geometry for serrations in blades.
