Patent ID: 8646709

Claim:
A jaw set for demolition equipment, wherein the jaw set is made up of a first jaw and a second jaw and, wherein at least one jaw rotates relative to the other jaw about a rotational axis, the jaw set comprising: a) a first jaw blade extending from a front end of the first jaw to a back end of the first jaw proximate to the rotational axis, wherein the first jaw blade has a front section and a rear section forming an obtuse angle relative to the front section defining an apex therebetween; i) at least one blade insert secured to each of the front section and the rear section of the first blade, wherein each blade insert has a longitudinal axis extending along the length of each insert; ii) wherein at least one blade insert of the front section has a cutting surface with grooves spaced along the longitudinal axis to provide a serrated cutting surface; b) a second jaw blade extending from a front end of the second jaw to a back end of the second jaw proximate to the rotational axis; i) at least one blade insert secured to a section of the second blade, wherein each blade insert has a longitudinal axis extending along the length of each insert; and ii) wherein at least one blade insert of the section has a cutting surface with grooves spaced along the longitudinal axis to provide a serrated cutting surface; c) wherein the first jaw blade and the second jaw blade rotate relative to one another to function as a shear; and d) wherein in a closed position, the cutting surface of the blade insert of the front section of the first jaw overlaps with and forms an acute angle with the cutting surface of the blade insert of the section of the second jaw blade.
