| 5. |  |
HEAT TREATMENT Heat treatment & tempering should be made at appropriate temperature for the best Rockwell hardness. Normal temperature for the heat treatment is set at 950℃ to 1070℃ (1742F to 1958F) & 450℃ to 550℃(942F to 1022F) for tempering. |
| 6. |  |
AUTO & SEMI-AUTO GRINDING This process includes surface grinding & perimeter grinding in accordance with the sizes requested in the CAD. |
| 7. |  |
BLADE GRIND Flat & bevel of blade is refined by fine grit paper. |
| 8. |  |
ASSEMBLY All the parts are assembled into a knife |
| 9. |  |
Pivot pin & lock bar pin are fastened by the rolling vibrator. |

KNIFE GRINDING Perimeter of the assembled knife is sanded off by the belt grinder. The grit number nomally used for this process is from #60 to #240.Polishing compound is used if finer finish needed. |
| 11. |  |
CLEANING The finished knife is washed in the high frequency vibration washer. |
| 12. |  |
HONING Cutting edge is put by a grinder wheel first. Then polished with a leather wheel to remove burrs on the cantle all through the belly, but the burrs on top of cutting edge should not be removed completely. Precise bevel angle & cantle width are requested. |
| 13. |  |
