Abstract

A wire cutter includes two jaws pivotably connected with each other and each jaw has a curve cutting edge which includes a cutting portion which includes a first section, a second section and a third section which is located between the first and second sections. Each of the first section and the second section has a first side surface and a second side surface, and a first angle of 60 degrees is defined between the first side surface and the second side surface. The third section has a third side surface and a fourth side surface, a second angle of 35 degrees is defined between the third side surface and the fourth side surface. The wires are pushed toward the second sections and cut by the second sections.

Claims

1. A wire cutter comprising:

two handles and two jaws connected to two handles respectively, the two jaws pivotably connected with each other, each jaw including a curve cutting edge which includes a base portion and a cutting portion which is connected to the base portion, the cutting portion including a first section, a second section and a third section which is located between the first and second sections, each of the first section and the second section having a first side surface and a second side surface, a first angle defined between the first side surface and the second side surface, the third section having a third side surface and a fourth side surface, a second angle defined between the third side surface and the fourth side surface, the second angle being smaller than the first angle.

2. The wire cutter as claimed in claim 1, wherein the first angle is 60 degrees and the second angle is 35 degrees.

3. The wire cutter as claimed in claim 1, wherein the base portion includes a fifth side surface and a sixth side surface which is connected to the first side surface and the third side surface, a third angle defined between the fifth side surface and the sixth side surface and the third angle being 45 degrees.

4. The wire cutter as claimed in claim 1, wherein the two jaws each include a straight cutting portion.
