Can Opener

Using tin cans as a method of food preservation started as early as the 1770s and a patent was issued for tin food cans in 1810, but the first dedicated can openers weren’t invented until the 1850s. Prior to the advent of the can opener, people used hammers and chisels to open their cans.
