As explained above, according to the hook handle processing method of the present invention, the blade part 8 which forms a pair of vertical saw and horizontal saw,
In a method of processing a hook handle using a pattern cutting machine equipped with a handle 8 on the left and right, the vertical saws 6, 6 are set in advance in a substantially V-shaped plane, while the horizontal saws 7, 7 are set in a flat position, respectively. After that, vertical saws 6, 6 are used in the processing process.
The machine can be machined by simply adjusting the workpiece once to the flat or dovetail position and moving the workpiece 19 using the vise 18. Therefore, the conventional method eliminates the complicated multiple vertical steps. This has the advantage that saw adjustment work can be omitted and the workability and work efficiency of the hook handle can be significantly improved compared to the conventional example.
