Skin incisions can be made using the flat of the blade with a fingertip grip or the tip of the blade using a pencil grip.
The fingertip grip is useful for long incisions while the pencil grip is helpful for delicate or non-linear work. In all cases it is important to know where the tip of your blade is. Control the depth and keep the blade as flat as possible. If movement is possible (standing surgery or teat surgery) or if the tissues are of unknown depth, a groove director can be inserted in the tissue plane to create a barrier and guide the depth of the cut.
