Blade shears are similar to scissors, and although most have the hinge at the back of the shears rather than the center, some still have the hinge in the center, e.g. Jakoti shears. More recent design improvements using a acetal bearing system fitted with superior wear resistant tool steel blades has greatly increased the longevity of the shears.
In 2006 and 2007 the company brought sewing shears, utility knives, chef shears, hobby knives and a titanium-bonded, spring-assisted pruner to market. [ 7 ] In 2008, Clauss introduced the SpeedPak utility knife and its replaceable cartridges with ten titanium blades, having won a Good Design Award from the Chicago Athenaeum, Museum of ...
The plowshare itself is often a hardened blade dressed into an integral moldboard (by the blacksmith) so making a unified combination of plowshare and moldboard, the whole being responsible for entering the cleft in the earth (made by the coulter's first cutting-through) and turning the earth over.
Shearing, also known as die cutting, [1] is a process that cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations. [2]

Dressmaker's shears have a long blade, typically 7–10 in (18–25 cm), for cutting out fabric. Blades are tapered, with one pointed and one rounded tip; the blunt tip prevents fabric from snagging on seams and threads. Blades have a "knife edge": the top blade is set at an acute angle which allows the scissors to cut through fabric easily.
A 5-degree shear angle decreases the force by about 20% [citation needed]. The amount of energy used is still the same. The moving blade may also be inclined 0.5 to 2.5°, called the rake angle, to keep the material from becoming wedged between the blades. However, raking the blade compromises the squareness of the edge. [4] The machine ...
