A pair of scissors consists of two pivoted blades. In lower-quality scissors, the cutting edges are not particularly sharp; it is primarily the shearing action between the two blades that cuts the material. In high-quality scissors, the blades can be both extremely sharp, and tension sprung – to increase the cutting and shearing tension only ...

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.
