1. A downhole cutting element, comprising:
a cutting table including a cutting face defined by a surrounding edge;
a fluid passage extending through the cutting element;
an aperture defined in the cutting face proximate the edge, the aperture operatively coupled to the fluid passage through an orifice, the orifice having a major cross-sectional dimension smaller than a major cross-sectional dimension of the fluid passage and smaller than a major cross-sectional dimension of the aperture; and
an abrasive particle inlet tube coupled between an abrasive particle reservoir and the aperture.
