The first can/tin opener wasn’t invented until about 75 years after canned food started being produced. During that time, people used hammers and chisels to open cans.

Another comment presented this same fact, but the years is 30 instead 75. Heck, what’s the truth.

To be fair the other commenter said 30 years after the can was invented, so maybe it goes like this:
Can food starts being processed -> 45 years later can is invented -> 30 years later can opener is invented
