👉 The arthritis weapon, also known as the "Arthritis Knife" or "Rigid Finger," is a modified tool designed for individuals with severe arthritis to perform everyday tasks. It typically consists of a short, rigid finger or a specialized grip that can be attached to a handle, providing a firm and stable tool for cutting, opening packages, or other activities that might be challenging with a regular hand. The design allows users to maintain a natural grip and leverage, reducing the strain on arthritic joints while still enabling them to perform necessary tasks independently.
