Why would tools with bigger handles, like a can opener or a toothbrush, be easier for an arthritis patient to hold?

These tools are easier for an arthritis patient to hold because they have a long handle, which makes less difficult to use it.

There are several items that an arthritis patient can use to live "easier". However, common tools tend to be small, which makes them more difficult to grab, because requires more strength and pressure, provided by tendons and joints, causing pain to arthritis patient, because their bones density is lower, which makes them weaker. So, a "solution" to this is using bigger tools, specials to these bone disease, a can opener or toothbrush are examples of it. Other items that help arthritis patients could be jar openers, chair extenders, and items that need less pressure and strength to be used.
