Sidney Oldall Addy, The Hall of Waltheof — XXV. Other Traces of the Norsemen (1893)
“ I have borrowed my last two examples from a parish which forms one of the boundaries of Hallamshire on the south, but they are near enough to be used as arguments in favour of the Scandinavian influence which prevailed in this district.In the town and neighbourhood of Sheffield the student of dialect will sometimes meet with words of Scandinavian origin, as for example "wheelswarf." Every Sheffield man has heard of Jack Wheelswarf, the local alias of a grinder. Wheel-swarf means wheel-dust, or dust from a grinding wheel, svarf being the Old Norse word for file dust. ”
