Manual scissors for metal – what is important to know about them

In the toolbox of the carpenter-finisher tool, there is always a place for metal scissors. Their main purpose is cutting a metal profile or metal. Today there is a huge variety of such tools. Today manual scissors are made of various materials, and they have long ceased to be monolithic. Their handle is made of metal, which is covered with PVC on top, alloy steel is used to produce cutting jaws. Therefore, the weight of modern scissors is very small, especially when compared with their predecessors. The lever has a design that allows you to use scissors with maximum convenience. Cutting with such scissors does not require much effort.

Types of Hand Shears

Scissors for metal can be ordinary or have a linkage. For conventional scissors, the handle and cutting edge are made from the same workpiece by forging. When using them, the cutting force depends on the ratio of the length of the handle of the tool and its cutting edge.

Manual scissors with lever gear have a handle and a cutting head. Each of these parts is articulated, which allows you to additionally create a lever transmission force. Therefore when using manual scissors of this type, the applied force when cutting metal is significantly reduced.

The difference in manual scissors for functional purpose

Scissors can be straight through or for direct cutting. This tool has long blades that allow with minimal effort to accurately and quickly cut metal along the entire length.

There are also ideal scissors, which are a universal tool. They can be used for continuous continuous cutting of metal, as well as for cutting small and large contours or radii. Work with their participation can be performed both in the middle of the sheet, and from the edges when the edge is cut off. Undoubtedly, perfect scissors can also be used for simple edge cutting.

Manual scissors for metal are best suited for making small small radii. Their blades have a filigree shape, which allows this tool to cut out the narrowest figures or curves.

Scissors can be right and left

Some may come to the misconception that left-handed scissors are for left-handed people, and right-handed ones are for right-handed people. By the way, if we are talking about scissors for direct cutting, here it is the other way around. With direct long cutting, it is very important to see the marking line. To do this, the right-hander will be much more convenient to perform the operation with left scissors. Although, in general, the scissors are separated by the location of the lower cutting edge: for the left scissors, it is on the left, and for the right – on the right.

The right scissors are made and sharpened in such a way that with their help the right radii are perfectly cut when the arc is executed from left to right. But the radii from right to left are preferably performed with left scissors. In the case when the right-hander will cut with the right scissors, his movement will be directed from the wrist to the outside. And in the case of using left scissors – from the wrist inwards.

Pay attention to the quality of the scissors

The reliability and life of the cutting edges are directly dependent on the quality of the steel and its processing, which was used to make the tool. High-performance manual shears for metal with cutting edges HSS made of steel with increased strength meet all standards and requirements.

ERDI manual scissors with a lever transmission use a forging die made of high-quality steel for the manufacture of cutting heads. An inductive method is used to fix the blades, due to which the products are highly durable, and the edges of the cuts have no burrs. Their ergonomic handle is protected against slipping and has a plastic coating. And steel nickel-plated handles have a rigid structure.

Having reviewed the features manual scissors for metal, You will know what to look for when choosing them. So feel free to go to the hardware store in search of the desired hand tool.
