The third outer surface intersects the first outer surface and the second outer surface to define an extrusion-acting portion having an extruding portion. The workpiece can be used to form a cutter or a trimmed portion thereof. Accordingly, rapid production of cutters by molding machines can be realized, and blades of the molding machine for machining a produced cutter become readily replaceable. While a blade portion is machining, the extrusion-acting portion is applied to support and guide the workpiece, such that the surface machined by the blade portion can be extruded and polished simultaneously. Thus, machining qualities of the cutter, including finish, straightness and roundness, manufactured by applying the workpiece for the molding machine can be significantly improved. ## Claims ### Claim 1 A workpiece applied for use with a cutting machine, comprising: a first arm, extending along a first-arm axial line, comprising a first blade end, a first connecting end, and a first extruding portion between said first blade end and said first connecting end; a second arm, extending along a second-arm axial line, comprising a second extruding end, a second connecting end, and a second blade portion between said second extruding end and said second connecting end, wherein said second connecting end connects to said first connecting end, and said first-arm axial line and said second axial-line are angled between 0° and 180°; and at least one assembly portion; wherein said workpiece attached to an object via the assembly portion and a fixation part. ### Claim 2 (depends on 1) The workpiece of claim 1, characterized in that an engagement means between the assembly portion and the fixation part is a manner using a screw and a thread hole, a rivet and a hole, or a mortise and a tenon. ### Claim 3 (depends on 1) The workpiece of claim 1, characterized in that the workpiece includes the first arm, the second arm and at least one connection hole, the angle between the first plane having the first-arm axial line and the second plane having the second-arm axial line being ranged between 0° and 180°. ### Claim 4 (depends on 3) The workpiece of claim 3, characterized in that the connection hole is located at the first arm. ### Claim 5 (depends on 3) The workpiece of claim 3, characterized in that the connection hole is located at the second arm. ### Claim 6 (depends on 3) The workpiece of claim 3, characterized in that the workpiece includes two said connection holes located respectively at the first arm and the second arm. ### Claim 7 (depends on 1) The workpiece of claim 1, characterized in that: the first arm, having thereon at least one first connection hole;
