Flail

Threshing and Post-Harvest Processing Implements

A flail is a hand tool used for threshing, the separation of grain from its husk, made of a long wooden handle joined to a shorter striking club called a swingle or swipple by a length of rope or leather cord so the striking end swings freely. A thresher gripped the handle and swung it so the swingle struck piles of harvested grain, loosening the kernels from the husks and straw, with the tool's exact dimensions varying by the grain worked and the region. The flail was the standard method of threshing for centuries before combine harvesters displaced it, though it survives in narrow niches, including Minnesota rules that still permit a hand flail no longer than 30 inches for harvesting wild rice from public waters.

the mechanical threshing machine displaced hand flailing for the same task, grain separation from the stalk

winnowing is the step that follows flailing, separating grain from the chaff the flail loosened

Entity-backed identity for the power-source enum value this implement already carries, resolved to an agriculture concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The power-source fact itself stays on the implement unchanged.
