Abstract

Abstract This invention relates to manual cutting implements for grooming and styling hair. A cutting implement having a unitary blade and shank attached to an elongated handle is provided which is particularly adapted to the trimming and shaping of beards, moustaches, sideburns and the like. The shank extends angularly away from the axis of the handle to a union with the blade wherefrom the blade appends angularly towards the handle and terminates at an oblique cutting edge, extending across the width of the blade. The ends of the blade project beyond the sides of the shank thereby exposing the ends of the cutting edge to the view of the user. Apparatus are provided for steadying the user's hand and controlling the pressure of the cutting edge against the surface in contact with the blade.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 319 words
A hair trimmer with an unguarded cutting edge, particularly adapted for grooming and shaping beards, moustaches, sideburns and the like, comprising: an elongated handle; a unitary blade and shank constructed from a strip of metal of uniform thickness, one end portion of the shank aligned with the axis of the handle and attached to the upper end portion of the handle, the remaining portion of the shank extending obliquely from the other shank portion to a union with the blade wherefrom the blade of a width greater than the width of said shank appends angularly downward towards the handle and terminates at an oblique unguarded cutting edge, said cutting edge being within the inner surface of the handle whereby said cutting edge is protected against damage when said hair trimmer is rested on said inner surface; a finger rest on said shank whereby the forefinger of a user is brought to bear for steadying the user's hand and controlling the pressure of the cutting edge of the blade against the surface in contact with the cutting edge; a pair of opposing notches in corresponding sides of the upper end portion of the handle for receiving the lower end portion of the shank; a rib in the upper end portion of the handle, said rib being formed by the interior sides of the notches and having tapered sides and an arcuate shaped projection at the upper portion thereof; and a slot in the lower portion of the shank, said slot having a shape corresponding to the shape of said rib whereby the shank is assembled to the handle by engaging the lower portion of the shank with the notches of the handle and forcing the rib and arcuate projection thereof into engagement with the slot and arcuate opening thereof, said shank being sufficiently resilient to engage the arcuate projection of the rib with the corresponding arcuate opening of the shank.
