Littauer Spencer Stitch Scissor 3.5": Working End Length 3 cm, Net Weight of Instrument 0.59 oz.: Littauer Stitch Scissors are primarily used for suture removal. These scissors have a small hook shaped tip on one blade that slides under sutures to slightly lift them before cutting for removal. This hook also holds the suture so it does not slip off the blade of the scissors prior to cutting. Littauer Stitch Scissors are most commonly available in the length of 3-1/2 inches, therefore, they typically have larger, less delicate tips than Spencer Stitch Scissors, and are used for removing larger sutures. They should not be used for cutting tissue. This product is straight with smooth, blunt/blunt tips and a length of 3-1/2 inches.
