Tool cores may have removable sections, which may be removable without damaging, cutting or severing attachment configurations for the removable sections. The removable sections may be handled simultaneously. Moving parts used to facilitate removal of the removable sections may be secured in a pre-loaded configuration.

A unique design is provided that increases the strength and extends the life of an asphalt saw blade. The asphalt saw blade may include a main body, outer plates and cutters that are secured to the main body and outer plates via a notched interface. The cutters can include cutting elements and a plate that reinforces the cutting elements while also shielding the cutter's main body from wear.

A harvesting knife has a base body, which is configured to be applied in a manner rotating in a machine around a drive rotational axis allocated to said base body, and has a plurality of teeth on its circumference

wherein, prior to a first application, at least one of the teeth has at least one cutter formed thereon.

Disclosed is a circular saw for cutting metals, the circular saw including a body formed in a disk shape; a plurality of saw blade support portions protruding to the outside of a disk along the circumference of the body and integrally formed with the body; a plurality of cutting tips including an upper portion including a cutting edge formed on the upper end of a surface facing the rotation direction of the body, a lower portion extending from one end of the upper portion toward the center of the body, and a stepped portion formed between the upper portion and the lower portion; and a plurality of seating portions formed to be recessed from the saw blade support portions toward the center of the body and including a space for seating each of the cutting tips, wherein the upper portion is thicker than the saw blade support portions, the lower portion and the saw blade support portions have identical thicknesses, and the stepped portions of the cutting tips are spaced apart by the same distance from the center of the body.

A saw blade includes an elongated body extending along a longitudinal axis and having an elongated cutting edge. A first hard metal strip is attached to a first portion of the cutting edge and includes at least one first full hard metal cutting tooth that is set left at a first angle relative to a vertical axis of the body that is generally perpendicular to the longitudinal axis. A second hard metal strip attached to a second portion of the cutting edge and includes a second full hard metal cutting tooth that is set right at a second angle relative the vertical axis.
