What is unique about a C cane?

A C cane is characterized by its distinctive handle shape, which features a straight portion with a curved end. This design helps to provide a comfortable grip for the user, promoting better control and leverage when walking. The unique handle shape can also enhance the cane's stability as it can better accommodate various hand positions, allowing for a more ergonomic use.

In contrast, the other options describe features that are not typical of a C cane. Lightweight plastic isn't a standard material for C canes; they are often made of metal for durability. Canes with four legs are generally referred to as quad canes, which provide enhanced stability compared to the single-point design of a C cane. Lastly, while canes do provide support, a C cane does not typically have the same level of weight-bearing capacity as other types of assistive devices designed specifically for that purpose, such as walkers.
