Take a look at the last line in the text below. Is there still a
dispute or has it been settled?

strigil
"ancient tool for scraping the skin after a bath," 1581, from L.
strigilis "horse-comb," from stringere (1) "draw along a surface,
graze, wound, strip off, rub," from PIE base *streig- (cf. L. striga
"stroke, strike, furrow," stria "furrow, channel;" O.C.S. striga
"shear;" O.E. stracian "to stroke;" Ger. streichen "to stroke, rub").
Etymologists dispute over whether this is connected to L. stringere
(2), root of strain (v.).
