    Is that really a shear? The only place the two blades come together like a shear is at the bottom, and it does not look like that do bypass each other.

    Just curious. Impressive whatever it is called.

    Not really sure what this machine is called, hemmjo. Just went with "shear" per source. Looks like a guillotine though. Perhaps someone in the industry can enlighten us.

    This is the way I have always thought of the way machines were named or their cutting action was described.
    In the dictionary the word shear can be a verb or a noun. In the world of machines this is also true, but the word shear becomes a descriptive noun when other words to describe the machine are omitted. Often 2 blades are connected together by a single pivot and simply called a shear. The movement or action may be additionally described as a scissor a shear may also have cylindrically shaped blades which would make it a rotary shear There are more way to describe a shear as well.
    The word guillotine is usually thought of a machine with a blade mounted vertically and dropped or moved by force to cleave or sever an object in two when 1 blade passes the other causing a shearing or cutting action.
    A lot of machines are called guillotine shears describing the movement or action of the blades, or simply a shear. Cutting machines with blades connected by a pivot are often called scissor shears, or simply a shear as well. SO, I would guess that either term for the machine in question could be both technically correct and technically wrong depending on one's perception of how it is named.
