Additionally, butt hinges are more able to handle expansion and contraction, making them more resilient to the effects of extreme temperatures.
Furthermore they are designed to be placed on recessed surfaces. They are not visible when the door opens or closes. This gives a smoother appearance and a more refined look. It is possible that they will require routing to create an even finish.

Some hinges with butts utilize a ball bearing between the knuckles to reduce friction. These hinges are perfect for heavy-duty, high-use doors. They also come with a pin that is fixed, which makes them ideal for doors that can't be opened by removing the pin.
Other types of butt hinges are a plain bearing that is grease-packed, which reduces friction by permitting the hinge to move with less force. These are suggested for lighter uses, including cabinet doors. These pins are also available with spin-ends that ensure the pin will remain in place.
