Pliers

A pliers (1), comprising:

• a first pliers body (10), comprising a first handle (11) and a first clamp (12) connected to a front end of the first handle (11), wherein a first pliers knife (13) and a first pliers back (14) are disposed on opposite sides of the first clamp (12);
• and
• a second pliers body (20), comprising a second handle (21) and a second clamp (22) connected to a front end of the second handle (21), wherein a second pliers knife (23) and a second pliers back (24) are disposed on opposite sides of the second clamp (22), and the second clamp (22) is pivotally connected with the first clamp (12) to make the first pliers knife (13) be connectable with the second pliers knife (23);
• wherein, one of the first pliers back (14) and the second pliers back (24) comprises a chipping blade (50) configured in a concave arc shape to perform chipping to a workpiece (2) especially on a middle part thereof without causing damage to the workpiece (2);
• wherein the chipping blade (50) comprises an arc-shaped recess (51) and a straight cut (52) extended from the arc-shaped recess (51);
• wherein the arc-shaped recess (51) comprises a blade angle (A) varied on different locations, and a range of the blade angle (A) is equal to or greater than 120 degrees and equal to or less than 135 degrees, which is less sharp so as to provide a safety use, and a maximum value of the blade angle (A) is located on a bottom of the arc-shaped recess (51);
• wherein the straight cut (52) comprises a cut angle (B), and a range of the cut angle (B) is equal to or greater than 85 degrees and equal to or less than 90 degrees, thus an operation of chipping is realized mainly at the bottom of the arc-shaped recess (51) to avoid injury when a user touches an edge of the chipping blade (50).
