(2) Blank shaping (thickness repair)-drilling center hole-rough scraping (leveling and matching)

(3) Forming milling (milling back, teeth, circle and back teeth by milling machine)-fine scraping (smooth and flat, accurate size)

(4) Two pieces matching-chamfering (edge milling)-knife edge-riveting

(5) Fitter shaping (cutting edge dislocation trimming)-grinding (grinding wheel rivet flattening, grinding shape and neck grinding)-drill bit.

(6) White finish (flatness of pliers handle, size of rear opening, opening gap)

(7) Heat treatment (above HRC42)

(8) Black finishing (elasticity and swing)-fine grinding (both sides)

(9) High frequency heat treatment of cutting edge (HRC48-50)
