The bionic hand replacement is common among industrial and office workers alike, as it allows for the installation of limb upgrades, such as built in toolkit, finger extension etc. The hand is like the full arm replacement but replaces only the hand from the wrist and down, rather than the full arm. Like the arm, the hand has limited dexterity and the sensors aren't as sensitive as a natural hand, giving you a +1 difficulty on checks requiring manual dexterity or delicate sensing. Because of the lower arm not being replaced, the hand offers no increase in strength, as it relies on the body's natural musculature to actuate.
