Abstract
A cutter for wall papers comprises a triangular grip and a sheath embedded therein for slidably holding a cutting blade. According to the invention, a base of the triangular grip defines a slide edge extending at an acute angle with the cutting blade and having a V-shaped cross-section symmetrical with respect to a plane containing a cutting edge of the cutting blade, thereby uniformly trimming edges of the papers extending on a baseboard without requiring rulers to obtain aesthetical workmanship of interior finish work in buildings.
Claims8
A cutter for wall papers comprising a sheath receiving an exchangeable cutting blade slidably therein so as to extend and retract its cutting tip from and into said sheath, and a grip for holding said sheath embedded therein and substantially triangular whose base is its longest edge and defines a slide edge extending at a relatively small acute angle with a cutting edge of said cutting blade and having a V-shaped cross-section symmetrical with respect to a phantom plane containing said cutting blade extending slightly beyond a line of prolongation of said slide edge, said grip being formed in said slide edge with a notch near a rear end opposite to said cutting tip, and a frusto-conical roller freely rotatable in said notch and slightly extending on both sides of the slide edge, thereby reducing sliding resistance of the slide edge.
