Anvil scissors

from Wikipedia, the free encyclopedia

An anvil pruner is a scissors with only one cutting edge. They are often used as secateurs .

In the case of anvil scissors, a blade glides through the material to be cut while it is being cut and, as a counterpart, hits a smooth metal surface, the anvil. The sharpened blade makes a pressing cut.

In contrast to the anvil scissors, bypass scissors (bypass, German: bypass) such. B. the rose shears the clippings on a counter blade. The sharpened blade slides sideways past an opposing blade while cutting.

function

various anvil scissors

In contrast to a bread knife , the blade of an anvil scissors pushes through the cut material. When using the bread knife, it is a pulling cut, as the blade is pulled through the cut material (here: the bread).

With anvil scissors, on the other hand, the blade moves freely through the cut material without touching a counter blade or the like. At the end of the cut, the edge of the blade rests on the anvil. This is made of a material that is softer than the blade so that it is not damaged when it hits the anvil. Suitable materials for the manufacture of the anvil are plastic and aluminum , zinc , brass or bronze alloys .

The blades are made of hardenable carbon or chrome steels . The hardness of the blades is usually between 54 and 58 HRC .

In the case of anvil scissors, the function of cutting is also given if the blade moves slightly to the left or right while cutting. As long as the cutting edge hits the anvil at the end of the cut and forms a positive fit with it, the material to be cut is severed. In the case of bypass scissors, on the other hand, the blade must always be in positive contact with the counterblade, because otherwise the material to be cut will not be severed.

Because of this, the blades of anvil scissors can be ground thinner than the blades of bypass scissors. The thinner a blade is ground, the less it will split the material to be cut and the cutting force required for cutting is accordingly lower. Thanks to thinner blades, anvil scissors cut easier than bypass scissors. They are therefore particularly suitable for cutting thick branches and hard wood.

The LÖWE principle: The pulling cut against a fixed surface combines the pulling cut with a pressing cut. This is possible through an eccentric mounting of the knife lever to the support lever. When the scissors are open, the blade is longer than the anvil due to the eccentric mounting. When closing the scissors, the blade pulls back slightly when pushed through the clippings. The already lower effort required for cutting is thus further reduced.

history

The world's first anvil shears were developed and manufactured by Walther Schröder in Kiel (Germany) in 1923 . The scissors were given the product name "Original LÖWE" and have been sold internationally since 1925. The long-established company with headquarters in Kiel is still the world market leader with its anvil shears for professional wine , fruit and horticulture as well as for many different applications in industry and craft . Based on the cutting principle of the anvil scissors, there are many different models of scissors that are suitable for cutting profiles, strips, hoses and tubes made of materials such as plastic, rubber and wood. In the meantime, other companies also manufacture anvil shears, such as Edma , Bahco , Felco , Gardena , Wolf-Garten and Fiskars .
