Working hand
A working hand is a type of prosthesis in which function is paramount. With this prosthesis , in contrast to the artificial hand, no consideration was given to the aesthetic aspect of the prosthesis.
development
The working hand developed around the beginning of the 19th century and was the direct opposite of the jewelry hand . The material was selected according to functional criteria. This type of prosthesis did not catch on in the long term, as the general development of prostheses soon made it possible for the population to purchase more affordable prostheses that were not as functionally restricted as the working hands were.
functionality
The prosthesis was attached to the amputated arm, making it the easiest upper limb replacement for the poorer population. It was only used for work. For example, instead of a hand, tools were usually attached as prostheses and no consideration was given to the cosmetic aspect. So you replace the lost hand with a tool that is best adapted to the specific requirements. So you could usually just replace the tool with another tool if you wanted to do a different job.
