Ice cutting was a winter occupation of icemen whose task it was to collect surface ice from lakes and rivers for storage in ice houses and sale as a pre-refrigeration cooling method. Kept insulated, the ice was preserved for all-year delivery to residential and commercial customers with ice boxes for cold food storage.

Ice harvesting generally involved waiting until approximately a foot of ice had built up on the water surface in the winter. The ice would then be cut with either a handsaw or a powered saw blade into long continuous strips and then cut into large individual blocks for transport by wagon back to the icehouse.[1] Because snow on top of the ice slows freezing, it could be scraped off and piled in windrows. Alternatively, if the temperature is cold enough, a snowy surface could be flooded to produce a thicker layer of ice.[2] A large operation would have a crew of 75 and cut 1500 tons daily.[3]

This occupation generally became obsolete with the development of mechanical refrigeration and air conditioning technology.[4]

Ice cutting is still in use today for ice and snow sculpture events. A swing saw is used to get ice out of a river for the Harbin International Ice and Snow Sculpture Festival each year. A swing saw is also used to cut ice out from the frozen surface of the Songhua River.[5] Many ice sculptures are made from the ice harvested this way.
