A straight Mayo scissor is a heavy-duty surgical scissor with straight blades, typically used to cut sutures, fascia, and other tough materials at or near the surface. It is valued for strength, controlled cutting, and easy handling in general surgical work.Straight Mayo scissors are built with robust blades and usually made from surgical-grade stainless steel for durability and corrosion resistance. Their straight design makes them best for surface-level, straight-line cutting, especially where clear access is available.
