1. A releasable attachment comb for attachment to a hair cutting device having a cutting element , the attachment comb comprising:
a support frame comprising a support bar , and first and second clamping elements located at respective opposite ends of the support bar, configured to clamp the attachment comb about ends of the cutting element in use;
the first element having a first interior face and the second clamping element having a second interior opposing the first interior face, the first interior face comprising a first set of locating notches, the second interior face comprising a second set of locating notches, each of the first and second set of locating notches being configured to locate engaging parts of respective ends of the cutting element, the first and second set of locating notches defining a clamping plane therebetween;
the attachment comb further comprising an array of comb teeth mounted to the support bar between the first and second clamping elements
wherein each comb tooth of the array of comb teeth has a substantially triangular shape, each comb tooth having a rear edge, a skin engaging lower edge, and an upper sloped edge, wherein a first end of the skin engaging lower edge meets with a first end of the rear edge at a rear lower corner of the comb tooth while a second end of the rear edge and a second end of the skin engaging lower edge join to respective ends of the upper sloped edge, the underside lower edge defining a skin engaging contact area;
wherein the first and second set of locating notches define between the first and second set of damping elements, a series of clamping positions for the cutting element, arranged at multiple positions along the clamping plane wherein he clamping plane is sloped with respect to the skin engaging contact area; and
wherein the clamping elements are at least partially displaceable away from one another to permit in use release and slidable advancement of the cutting element along the clamping plane between the clamping positions;
wherein the clamping elements are flexible about the support bar to permit bending of an opposed set of first end portions of the clamping elements away from one another, by applying an inward punching action at opposed second end portions of the clamping elements;
wherein the clamping elements form end panels that extend around or encompass the substantially triangular shape of the array of comb teeth; and
wherein the series of clamping positions for the cutting element defined by the first and second set of locating notches of the attachment comb cooperatively include a series of slanted clamping positions for holding a received cutting element extending diagonally between the clamping elements, wherein the series of slanted clamping positions defined by the notches are aligned in a row which runs along a slanted axis across the interior face of the clamping elements.
