1.Using techniques of fine blanking to cut the edge neat and smooth plus heat tratment to obtain highly stable quality. Features: Using the fine blanking process, precise finished components can be produced with inner and outer forms that are cleanly sheared over the total material thickness while achieving superior overall flatness. This process eliminates the need for costly secondary operations such as shaving, milling, reaming, broaching and grinding. |

| 1.Partly trimmed surface |
2.Imprecise concentricity is formed because of separately punching holes unable to give the handle more torque, besides, loosing components inside the head of hnadle is apt to reduce the life of product. |
