Mayo scissors have semi-blunt ends, a feature that distinguishes them from most other surgical scissors. Curved-bladed Mayo scissors allow deeper penetration into the wound than the type with straight blades. The curved style of Mayo scissor is used to cut thick tissues such as those found in the uterus, muscles, breast, and foot. Mayo scissors used for dissection are placed in tissue with the tips closed. The scissors are then opened so that the tips open and spread out the tissue during the dissection process.
