Abstract: A new way of measuring leaf fracture toughness using a single inclined razor blade was researched and developed. The new method, named the Single Blade Cutting Method (SBCM), was capable of overcoming several limitations that beset current fracture toughness tests for biological materials, the most notably of which is high device friction. Tests conducted to determine its optimal tests parameters showed that the method worked best at small blade angles and intermediate gap widths. Comparison of the SBCM with scissoring using both biological and non-biological specimens showed that the SBCM tends to deliver results that are about 1.5 times lower than scissoring. This was attributed to the difference in sharpness of the two cutting implements, of which the razor blade is sharper. The SBCM was found to be a promising alternative testing method and should be a welcomed addition to the array of current measurement techniques.
