A method for manufacturing a blade of a cutting tool, in particular, a knife. In order to create a process with which influence is to be exerted in a targeted manner on the technological material properties of the blade and material chipping to be avoided, as well as permitting economical manufacturing, a process is carried out by treating a blade base material with a laser in a first process step along a curve contour determined by the final edge of the blade and, in a second process step, the edge of the blade is formed, in particular, cut to shape, along the curve contour determined by the final blade form inside the laser-treated area, or the blade base material is machined in a first process step by punching or trimming to form the final edge, subsequently the laser treatment is performed in a second process step on the narrow side forming the final edge and finally, in a third process step, the blade is formed, in particular, ground, inside the laser-treated area.

A blade of ceramic material is treated to enhance the strength and sharpness of the cutting edge. In one embodiment, ceramic particles along at least one margin of an edge-forming face are fused, such as by a laser treatment.

A utility blade for use with conventional retractable and fixed blade utility knives comprising a blade body having a generally trapezoidal configuration defined by a cutting edge, an opposite back edge, a pair of opposing side edges and a pair of cutting points defined by the points of intersection between the side edges and the cutting edge. The blade further defines a pair of score lines, each proximate to one of the side edges. The score lines enable the user to remove a dulled or damaged cutting point, which in turn provides the user with two additional cutting points defined by the points of intersection between the score lines and the cutting edge. Further, the blade is configured with one or more notches strategically located on the back edge of the blade, such that each cutting point can extend from the utility knife at approximately the same distance.

A metallic housing utility knife and method for making the device with a soft over molded elastomeric cover to provide blister free comfort and slip proof safety.

The present invention relates to a baler ejection system that may be used with an agricultural harvester, such as a round baler, waste baler, combine, or cotton harvester. More particularly, the bale ejection system uses the motion of two pairs of parallel arms that extend transversely from the sidewalls of a bale chamber at two sets of distinct pivot points. When activated by the operator of the bale ejection system, the two pairs of parallel arms raise simultaneously to expose an outlet through which the bale may be ejected. The bale ejection system is designed to allow a larger outlet for the bale evacuation as compared to existing bale ejection systems that employ circular motion to expose the bale outlet. A formed bale may become ejected by one or more conveyer belts that exert a rearward force on the bale within the bale chamber. The bale becomes ejected through the outlet onto a field upon which the bale ejection system is operating or into a second bale chamber.
