1) Occupational term for someone who made a living by sharpening scythes.
Until well into the eighteenth century most Hallamshire metal workers who needed to grind their own wares rented space at grinding wheels, and only scythe-grinding was a specialist occupation. In Derbyshire, a scythe-mill was established at Holbrook in 1489 but the first references to the occupation are much later: 1603 Robert Barnes, scythe grinder, Norton. However, it was an established craft in Sheffield later that century: 1674 Rob. Hawksworth, Heeley, scythgrinder
