Abstract: A suture cutter having a handle and a barrel with a movable cutting head on the barrel, and the barrel supporting a stationary cutting edge and a movable cutting edge. A movable support carries the movable cutting edge and includes a surface spaced from the stationary cutting edge a selected distance. An abutment wall spaced from the stationary cutting edge at the selected distance provides for snugly restricting movement of the moving cutting edge away from cutting contact with the stationary cutting edge while cutting the suture. Recesses are defined on a guiding support surface along which the movable cutting edge slides when the handle is actuated, allowing for sharpening of the moveable cutting edge when said edge is retracted proximally.
