A surgical probe, comprising: a tubular body defining a cutting aperture at a first end of the tubular body, the tubular body defining a longitudinal axis; and a scissor assembly received at least partially within the body and extending along the longitudinal axis, the scissor assembly including: a first blade fixed relative to the tubular body, the first blade including a body portion and an end portion; and a second blade configured to move longitudinally within the tubular body, the second blade including a body portion and a cutting edge at an end of the body portion, the cutting edge configured to cut material against the end portion of the first blade; wherein the first blade extends from the tubular body to define a neck portion between the body portion and the end portion, the neck portion defining a first width smaller than a second width of the cutting edge of the second blade; characterized in that the body portions of the first and second blades each define respective cross sections (X,Y) disposed in a plane normal to the longitudinal axis of the tubular body, the cross sections each defining centrally disposed edges (118,120) adjacent one another, and wherein at least one of the cross sections is asymmetrical about a line substantially parallel to the centrally disposed edges, wherein the cross sections are substantially defined by the centrally disposed edge, a pair of opposing lateral edges adjacent the centrally disposed edge, and a distal edge opposite the centrally disposed edge; and wherein the opposing lateral edges are formed by etching a sheet material, wherein opposing sheet surfaces include the centrally disposed edge and the distal edge prior to etching the sheet material. a tubular body defining a cutting aperture at a first end of the tubular body, the tubular body defining a longitudinal axis; and a scissor assembly received at least partially within the body and extending along the longitudinal axis, the scissor assembly including: a first blade fixed relative to the tubular body, the first blade including a body portion and an end portion; and a second blade configured to move longitudinally within the tubular body, the second blade including a body portion and a cutting edge at an end of the body portion, the cutting edge configured to cut material against the end portion of the first blade; wherein the first blade extends from the tubular body to define a neck portion between the body portion and the end portion, the neck portion defining a first width smaller than a second width of the cutting edge of the second blade; a first blade fixed relative to the tubular body, the first blade including a body portion and an end portion; and a second blade configured to move longitudinally within the tubular body, the second blade including a body portion and a cutting edge at an end of the body portion, the cutting edge configured to cut material against the end portion of the first blade; wherein the first blade extends from the tubular body to define a neck portion between the body portion and the end portion, the neck portion defining a first width smaller than a second width of the cutting edge of the second blade; characterized in that the body portions of the first and second blades each define respective cross sections (X,Y) disposed in a plane normal to the longitudinal axis of the tubular body, the cross sections each defining centrally disposed edges (118,120) adjacent one another, and wherein at least one of the cross sections is asymmetrical about a line substantially parallel to the centrally disposed edges, wherein the cross sections are substantially defined by the centrally disposed edge, a pair of opposing lateral edges adjacent the centrally disposed edge, and a distal edge opposite the centrally disposed edge; and wherein the opposing lateral edges are formed by etching a sheet material, wherein opposing sheet surfaces include the centrally disposed edge and the distal edge prior to etching the sheet material.
