The Ergonomic Handgrip and Underarm Pad: The handgrip and underarm pad would be made of soft, resistance materials such as silicone or foam to allow comfort in the area of the user's hands and arms. These parts are designed with contours to achieve a good grip and avoid slipping, enhancing users' experience for extended periods. Applying commercially available ergonomic parts, high comfort is assured. Furthermore, if wear occurs, easy replacement adds value to the product.

Fasteners and Adjustable Pins: The pins, screws, and rivets that support the crutch sections firmly hold them together in the conduct of the adjustable features. Manufactured from stainless steel or high-tensile alloy, they neither rust nor loosen after repeated readjustments. Standardization of the fasteners by buying from commercial sources would ensure ease in assembly, replacement convenience, and the overall robust structure for safety in walking with the crutches.
