Sharpening and Servicing Scissors

Sharpening & Servicing Scissors

Scissors sharpening & servicing is essential to keep your scissors at optimal performance, thus prolonging its life and minimizing the stress on your muscles. Below we can explain the three major edge types and the difference in the scissor sharpening methods.


  • Convex Edge: Most stylists prefer a CONVEX (Hamaguri or Clamshell) edge because stylists have been told that convex edges are better, and it is easier to go with the flow. There is no doubt that this type of edge is the sharpest of the three types, but it is not always the best edge for the job. For example if you require serrations then this is not the edge for you. To sharpen a true convex shear/scissor you should use a special flat hone machine to accommodate the seamless curved lines of the blade that run all the way to the edge.
  • Semi Convex Edge: The semi convex edge and convex edge are almost same part from there will be a distinct line where they have been sharpened. In practice there is very little noticeable difference. You can use normal sharpening machines for this type of edge.
  • Beveled Edge: The main difference is that this edge is thicker than a convex or semi convex edge and this thickness helps support the edge of the blade. This edge is not suited for the fine and acurate angles of the convex scissors, but is ideal for barbers and pet groomers where a harder wearing edge is preferred. Same sharpening method as the semi convex scissors edge.

  • Micro Serrated Edge: Normally found on bevel edge scissors or shears. The tiny teeth will hold hair as it is cut, and prevent it from sliding. Hence this type of scissors is preferred by barbers who use a "scissor over comb" style of cut and not suited for hairdressers who often like to slide cut.
