A cutting tool mechanism and cutting tool (11) including the mechanism (31), for cutting hard material such as concrete and stone is disclosed. The tool (11) has one or two blades (23), (25) each driven by a mechanism (31). Each mechanism (31) has an input coupling 35 for transmission of rotary motion from a motor, and an output coupling (141), (143) to transmit resultant orbital, oscillatory or impact motion to the blade (23), (25). A suspension or sliding coupling located between the output coupling (141), (143) and the blade (23), (25), is provided, through which motion to the blades is transmitted. The suspension or sliding coupling absorbs impacts of the blades with the material being cut, rendering the tool more controllable.

Embodiments relate generally to methods for extracting a core from a percussion side wall core bullet for a digital tomographic description and direct numerical simulations. A method for extracting a core from a percussion side wall core bullet for a digital tomographic description and direct numerical simulations includes pushing a free end of a wire of a wire saw through the core. The core is positioned within the percussion side wall core bullet. In addition, the method includes attaching the free end to a locking mechanism of the wire saw. Further, the method includes cutting the core from the percussion side wall core bullet. The method also includes removing the core from the percussion side wall core bullet.

A cutting tool includes a blade formed so as to extend in the width direction or length direction of a workpiece; at least one cutting tip formed so as to protrude from the lower portion of the blade so as to cut the workpiece by reciprocating by means of a swinging motion; and a brazing part formed between the blade and the at least one cutting tip so as to silver-braze the blade and the at least one cutting tip. The brazing part includes a first silver solder layer; a metal sheet layer formed on the first silver solder layer and having a melting point that is higher than a silver brazing process temperature; and a second silver solder layer formed on the metal sheet layer.
