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.
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 first one-man chainsaw was introduced in 1950, though it was relatively heavy. By 1959, the average weight was around 12 kg (today, chainsaws typically weigh between 4 and 5 kg, with heavy-duty models ranging from 7 to 9 kg), and it quickly gained attention. [16] McCulloch in North America started to produce chainsaws in 1948. The early ...
Telescopic handlers are forklift-like trucks that have a set of forks mounted on a telescoping extendable boom like a crane. Early telescopic handlers only lifted in one direction and did not rotate; [ 61 ] however, several of the manufacturers have designed telescopic handlers that rotate 360 degrees through a turntable and these machines look ...
