Pruning Depending on what you must prune, focus on three pruning tools: loppers, a pruning saw, and bypass hand pruners. Loppers are long-handled pruners for cutting branches of about 1/2-inch ...
The main distinction among loppers is between bypass and anvil types. Bypass loppers operate like scissors, except that they generally only have one blade that moves past a jaw or hook that has an approximately square edge that is not typically sharpened and is usually concave or hook shaped in order keep branches from slipping out of the jaws.
Use bypass pruners or loppers and cut branches at a 45-degree angle. Avoid heavy pruning, especially in conspicuous areas. New growth will not emerge from bare, old wood to hide any gaps that ...
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. [2]
The earliest tools were made variously of wood, flint, metal, tin, and bone. The development of metalworking, first in copper and later in bronze, iron, and steel, produced today's durable tools, including such efficient cutting tools as pruning shears (secateurs – for example anvil pruners), grass shears, and loppers.
String trimmers powered by an internal combustion engine have the engine on the opposite end of the shaft from the cutting head, while electric string trimmers typically have an electric motor in the cutting head, but there are other arrangements, such as where the trimmer is connected to heavy machinery and powered by a hydraulic motor.
