A Hills Hoist is a height-adjustable rotary clothes line, designed to permit the compact hanging of wet clothes so that their maximum area can be exposed for wind drying by rotation. They are considered one of Australia's most recognisable icons , and are used frequently by artists as a metaphor for Australian suburbia in the 1950s and 1960s.

At least seven hydraulic clothes hoists had been patented in Australia prior to Toyne's design.

Longer washing lines often have props holding up the mid-section so the weight of the clothing does not pull the clothesline down to the ground. More elaborate rotary washing lines save space and are typically retractable and square or triangular in shape, with multiple lines being used (such as the Hills Hoist from Australia).
The most popular material for handles of hand saws is applewood; in the early 1900s 2,000,000 board feet of applewood were used annually for this purpose. [2] Sometimes cultures developed two main types of saw teeth: the cross cut saw teeth and the rip saw teeth. [citation needed] These cut into the wood using different mechanisms.
A polesaw (also pole saw or giraffe saw) is a saw attached to a pole or long handle that is used for pruning tree branches that are beyond arm's reach. [1] [2] A polesaw allows its user to cut high branches without the use of a ladder. [3] Polesaws can be manual or motorized.
