Iris scissors, 4 1/2 straight s/b

4 1/2" Iris scissors, straight S/B are precision surgical scissors with straight blades, designed for fine, controlled cutting. The S/B likely refers to the sharp/blunt tip configuration, providing a sharp cutting edge on one blade and a blunt tip on the other for safety during delicate dissection in confined spaces, commonly used in ophthalmic and microsurgical procedures.
