1. Different shapes (shape characteristics): the jaws of pliers are slender, with V-shaped sides and zigzag overall. This design makes the pliers more flexible in thinning work and can better adapt to the narrow working space. But the lower jaw of the vice is arc-shaped, both sides are U-shaped, and the whole vice is arc-shaped. This design enables the vice to better meet the fastening requirements of larger objects, such as pipelines and large metal products.
2. Different scope of application (application field): Wire cutters are mainly used for thinning work and are suitable for fastening small parts. Because the jaws of wire cutters are slender, small objects can be easily clamped without damaging them. This makes pliers very useful in the fields of electronics, watches and clocks, jewelry and so on. In contrast, the vice is suitable for fastening large objects, such as pipes and large metal products. Because the jaw of the vice is wider, it can provide greater clamping force, which is suitable for working scenes with high requirements for strength and stability.
