Description

The present invention is generally directed to manicure or pedicure Manicuring implements including conventional fingernail files and emery boards generally include a flat abrasive surface for filing purposes. Such nail files and emery boards generally include an abrasive paper laminated to a flat substrate made of wood, compressed paper, plastic, foam or the like Also available in the prior art are fiat metal nail files which include a knurled or scored surface which defines the abrasive surface When using nail files users predominantly try to produce a curved nail shape due to the natural shape of the finger or toe. Present this requires them to move and or rotate either the nail or the file as they file Said actions require a high level of skill, increase the amount of time required to file a nail, require a high level of concentration and may result in repetitive strain injury (RSl) in professional manicurists Further more as most users tend to be one hand dominant the nail shape may vary from one hand to another Prior art has proposes a number of different solutions to this problem including completely round files US2225567, flexible files with large amounts of foam and files having longitudinal cross sectional curves GB 778517. These however have either damaging effects on the users nail as they do not conform to the shape of the nail during file due to a lack of flexibility, have storage and aesthetic disadvantages or more specifically only permit use of one side of the file as in GB 778517 Accordingly there is a need for a manicure device which removes the afore- mentioned disadvantages Therefore these and other objectives are provided for by an improved manicure device
