Surgical Scissors are typically either one of two designs. The Mayo is the general purpose Surgical Scissor in which the blade occupies approximately one third of the length of the scissor. The 14cm straight Mayo is the standard veterinary Surgical Scissor. The Metzenbaum is a finer lighter Scissor in which the blade occupies approximately one quarter of the scissor length. Using a 14.5cm Metzenbaum rather than a 14cm Mayo will give you a finer scissor but a similar working distance.
