A bench mounted sheet metal shears, is ideal for cutting sheet steel and other sheet metals, such as copper and brass.
The blades are designed to minimise the production of sharp burrs, on the edge of the sheet metal being cut.

Bench shears are normally used in preference to tinman’s snips, when the
a large size of sheet metal is being cut / shaped, which means greater control is required. The long lever handle, makes cutting thicker sheets easier.

Some bench mounted shears are also designed to cut round section metal.

For health and safety reasons, bench shears should have lockable blades. In this example, a padlock is used to secure a steel pin, which is pushed through the blade. This makes it impossible to operate the shears, until the padlock is unlocked and the steel pin removed. It is also advisable to wear leather gloves when handling sheet metal. The metal can have hazardous sharp edges, capable of serious injury.

 
 
 
In operation, sheet metal is placed between the top and bottom blade. The surface of the metal, should have been marked out, using a pencil or a scriber (engineers blue may also be used). The adjustable support is lowered to the surface of the sheet metal and locked in position. This ensures that the sheet metal is held firmly and less likely to slide about. The handle / lever is carefully, but firmly, pulled in the direction indicated by the arrows and the top blade moves downwards, cutting along the marked guideline. The blades operate a little like those of a scissors, but in this case cutting metal.
