Cutting with scissors such does not require much effort.

Types of hand shears

Metal shears may be conventional orlinkage. Conventional scissors handle and blade edge made of a preform forging method. Their use depends on the cutting force instrument handle length ratio and its cutting edge.

The difference between manual scissors on a functional purpose

Scissors can be looping or straight cut. This has a long-bladed tool that enable a minimum of effort to cut the metal over the entire length accurately and quickly.

To do this, right-hander will be much easier to perform the operation left a pair of scissors. Although in general the separation of shear occurs at the location of the bottom of the cutting edge: at the left of scissors it is on the left, while the right - right.

The right scissors sharpened and made in such aa way that with their help perfect cut right radii, the arc from left to right. But radii, right, left is preferably carried out with scissors. In the case where the right-hander will perform right cut with scissors, its movement will be directed outwards from the wrist. And in case of using scissors left - from the inside of the wrist.

Pay attention to the quality of scissors

The reliability and service life of the cutting edgesThey are directly dependent on the quality of the steel and its treatment, which has been used for the manufacture of tools. High-performance hand-held metal scissors with cutting edges HSS steel with increased strength to meet all standards and requirements.

The hand-held shears with ERDI linkage formanufacture of cutting heads used forging die made of high quality steel. To secure the blade using the inductive method, whereby products are characterized by high durability, and cuts the edges have burrs. Their ergonomic handle is protected from slipping and has a plastic coating. A nickel-plated steel handles have a rigid structure.
