A blade sharpener for sharpening an edge of a blade of a cutting instrument, comprising: (a) a frame having a first upright member, a second upright member disposed at right angles to the first upright member, and a base upon which the first upright member and the second upright member are mounted,
A blade sharpener for sharpening an edge of a blade of a cutting instrument, comprising: (a) a frame having a first upright member, a second upright member disposed at right angles to the first upright member, and a base upon which the first upright member and the second upright member are mounted, said base being attachable to a bench; (b) guide means attached to said first upright member and capable of guiding a sharpening tool over the blade of said cutting instrument at an appropriate sharpening angle, said guide means comprising an elongated member comprising a pair of parallel guides forming a longitudinal slot therebetween, and a channelled bar with a longitudinal slot, said channelled bar extending from the elongated member to form a “T”bar therewith, said first upright member having a rib, said rib slidably receiving said channelled bar to provide height adjustment for the elongated member; and (c) a blade clamping means for holding the blade of said cutting instrument at a prescribed angle relative to the guide means wherein the sharpening tool can be guided by the guide means over the blade at said appropriate sharpening angle, the blade clamping means having: (i) a first jaw comprising a relatively thin first end and a second end, a first surface and a second surface, said second surface facing in an opposite direction to said first surface, each of said surfaces extending between said first end and said second end, said first surface being substantially flat and said second surface having a ledge diverging from said first end towards said second end, a flange extending from a longitudinal edge of said first jaw and pivotally connecting said first jaw to said second upright member, whereby, in use, an angle of inclination of said first jaw can be pivotally adjusted through at least 180°in a plane substantially perpendicular to an edge of the blade of said cutting instrument; and (ii) means to clamp the cutting instrument against said first jaw at a location selected from a group consisting of the ledge, the first surface and the second surface whereby, in use, a blade of any cutting instrument selected from a group consisting of a knife, scissors, shears, clippers, an axe, a chisel, a saw and a chain saw, can be held in said blade clamping means at said prescribed angle to effect sharpening of the blade.
