A tin opener, typically a can opener, is assembled by connecting the main components: the handle, the cutting wheel, and the lever. The handle is attached to the lever, which pivots and allows the cutting wheel to puncture and cut the can's lid as the user turns the handle. The cutting wheel is secured to the lever and is designed to rotate smoothly while piercing the metal. Finally, all parts are fastened together, ensuring they operate efficiently and safely.

The primary function of the can opener is to open tin cans. Though the first tin can have been in use since 1772 in The Netherlands, the first tin can was patented in 1855, though earlier un-patented models may have invented.

Fulcrum I think.
In a tin opener, the fulcrum is typically located at the pivot point where the lever arm of the can opener meets the body or handle. This pivot allows the lever to rotate, enabling the cutting wheel to puncture and cut through the metal lid of the tin can. By applying force on the handle, the user creates leverage around this fulcrum to open the can efficiently.
The tin can opener was invented in 1858. This was necessary after the invention of the tin can 48 years earlier, in 1810.
Well, I'd call them a tab collecter.
