Parts of a Can Opener

- Apr 30, 2018-

Base or Handle

In manual, hand-held can openers, the handle allows the operator to keep the can steady with one hand by squeezing the handles together, so that the other hand can operate the crank. In mounted can openers, usually screwed into a countertop or wall-mounted, the base keeps the can steady and, in electric can openers, the built-in base helps maintain can position during opening.

Crank

Whether electric or manual, the crank operates the gear. Some wall- and counter-mounted can openers have an adjustable crank shaft to accommodate different sized cans.

Circular Knife or Blade

A round blade is used to pierce the metal and open the can in manual and electric can openers.

Knife Holder

The circular knife is held in place with a small metal dowel-like part and aligns the knife with the operational gear.

Gear or Feed Gear

A small gear moves the circular knife in both types of can openers. The gear is connected to an electric crank or by a manual crank, which is maneuvered by the operator.

Motor

In electric can openers, the motor operates the gear, crank and rotary knife.

Lid Magnet

In electric can openers, a magnet helps position the can during opening and holds onto the metal lid once it is removed from the can.
