The device has three different parts: a can opener to open cans, a bottle opener to open bottles with twist caps and to open bottles with crown caps . In addition, a 3-in-1 opener is useful for people with limited mobility or hand strength, such as the elderly or people with arthritis. It can also be useful for people with reduced hand function.
In addition, a 3-in-1 opener can be useful in situations where no other tools are available, such as when camping or traveling .

In addition, the multi-cap, non-slip opener is a useful tool in the kitchen. It can make it easier to open bottles with wet hands or when the cap is over-tightened. It can also save time by requiring no additional tools or effort to open a jar or bottle.
