Device Details


The Customizable Beverage Can Opener provides a way for those with arthritis, low finger dexterity, low vision, or other related disabilities to open beverage cans with little strength or accuracy required. There are three different handles available for use with this device, hence the name “customizable”:

Base Can Opener:

The Base Can Opener has a sloped hole which fits over almost all beverage can tabs. The device includes a graphic that describes which side should be facing upwards when opening the can and an arrow pointing towards the can opening. The device is designed to be used on its own or with the handle attached, as described below:

Cylindrical Handle

Flat Handle

The Flat Handle is designed for someone with limited hand function and uses the wrist or elbow to open the can once the can opener is placed on the pull-tab.

Loop Handle

The Loop Handle is designed to open beverage cans without using fingers. The loop slides over the user’s hand, then the can opener can be used by lifting and twisting the hand.
