Abstract
In a nail file, the combination comprising (a) an elongated holder having an elongated handle, consisting of synthetic resin, said holder having relatively thin, upper and lower elongated flanges and an elongated medial web interconnecting the flanges adapting the flanges to flex relative to the web, (b) a resiliently flexible first sheet having an abrasive surface, (c) the sheet retained to one of the flanges so that said abrasive surface is outwardly presented, whereby the sheet when pressed against a fingernail flexes along with said one flange and assumes the contour of the fingernail, the sheet being elongated in the direction of the handle.

In a nail file, the combination comprising
- (a) an elongated holder having an elongated handle, consisting of synthetic resin, said holder having relatively thin upper and lower elongated flanges, and an elongated medial web interconnecting the flanges adapting the flanges to flex relative to the web,
- (b) a resiliently flexible first sheet having an abrasive surface,
- (c) the sheet retained to one of the flanges so that said abrasive surface is outwardly presented whereby the sheet when pressed against a fingernail flexes along with said one flange and assumes the contour of the fingernail, the sheet being elongated in the direction of the handle,
- (d) said holder being longitudinally elongated and having lateral width greater than its thickness, the sheet extending across the width of the holder,
- (e) said flanges having projections integral with their lateral extremities, said projections adapted to interengage and transfer loading from one flange to the other during said flexing, the flanges spaced apart between said projections and said medial web.
