WPI's Swiss Tweezer Set has five pair of tweezes with fine tips for precision work in microsurgery, microdissection, and applications requiring fine manipulation of tissue or small objects under a microscope. Some have fine, straight, pointed tips, one pair has flat, rounded tips, and one pair has fine curved tips. These are hand forceps with a spring action letting you pinch the blades together to control the amount of pressure used. They are manufactured from anti-magnetic, acid-resistant stainless steel, which is suitable for autoclaving or chemical sterilization. The acid-resistant, anti-magnetic alloy works well in an MRI environment. All of these surgical forceps are quality Swiss-made instruments.
