236:. On an anvil pruner, proper cutting is assured even if the blade swerves slightly to the left or right during cutting. As long as the blade meets the anvil at the end of the cut and fits tightly against it, the material is separated. For this reason, the blades of anvil pruners can be ground thinner than those on bypass pruners. The LÖWE principle – a drawing cut made against a fixed support – combines a drawing cut with a pushing cut. This is possible because the blade lever and base lever are connected by an eccentric bearing. When the pruners are open, the blade is longer than the anvil thanks to the eccentric bearing. When the pruners close, the blade draws back slightly while it pushes through the material. This reduces the cutting force needed to make a cut still further. Because they crush the stem they are cutting, anvil pruners are best for use on dead wood. 170: 146: 38: 490: 258: 242:
usually work exactly like a pair of scissors, with two blades "passing by" each other to make the cut. At least one of the blades will be curved: a convex upper blade with either a concave or straight lower one. Some bypass designs have only one blade, the lower jaw being broad (like an anvil) but

The world's first anvil pruners were developed and produced in 1923 by Walther Schröder in Kiel, Germany. The pruners were given the product name "Original LÖWE" and were distributed internationally as far back as 1925. Other companies producing anvil pruners include Bahco, Edma, Felco, Fiskars
