Theoretical dependences permitting todefine normal tensions in a cross-section of woodworking tools at the start-time of cutting with a sharp knife under different schemes of front surface load are developed. The leading factor determining the value of normal tensions arising in the cross-section of a wedge-knife from tangent (hogging) cutting force are discovered. The analysis of the previously developed formulas for defining the grade of knife's tip winding is presented.
