Abstract

An ergonomic hand instrument with a finger grip loop and a thumb grip loop also has a forefinger control surface on at least one of the instrument arms. The control surface may include a proximally facing curved wall surface to receive the distal end of the tip of the user's forefinger. Forward and downward pressure can be applied with the forefinger with improved control and stability.
