Other GripsFurther functions of your bebionic3 hand.Precision GripsThere are two variations of precision grip: precision open, where the remainingfingers stay fully open, and precision closed where the remaining fingers closefully.Precision is the best grip for picking up and manipulating small objects quicklyand accurately. Initially both the index finger and thumb close, the thumb pausesmidway whilst the index finger continues to close to grip the object. This makesit easier to position the fingers to pick up smaller objects.HookPartially closing the hand in powergrip will create hook grip, which isuseful for carrying a shopping bagor briefcase.Finger AdductionAs the bebionic3 hand closes thefingers move together naturally - thisallows thin objects, such as cutleryor a toothbrush, to be grippedsecurely between the fingers.Adduction grip is most functionalwith the hand in power grip, but itcan also be used with the hand inkey or tripod grips.
