the spring is released by a pressure of the thumb of the sound hand in twisting the artificial hand off. The hook and other tools have a lug at the end of the spindle or shank; after passing the shank through the hole in the center of the arm plate, it is turned to any desired position and held firmly in place with the wing nut, as shown in No. 310.
Some of the Implements
Some of the implements that may be attached in the wrist plate when the hand is removed are also shown in the illustration. All excepting the brush are made of steel, or other suitable metal.

Wrist Joint Amputations
These usually leave a stump somewhat larger at the end than immediately above (see No. 318, page 64), thus providing a means of securely applying the arm and keeping it in place without the necessity of attachment above the elbow, as shown in No. 319.
Attachments above the elbow may, however, be put on if thought best, and for amputation at or a short distance above the wrist it is preferable to make the connection at the elbow with leather straps, as shown in No. 320, rather than with steel joints.
The socket of any arm for amputation between wrist and elbow will be made to lace if desired.
