Why is a jigsaw puzzle called that?

The name "jigsaw puzzle" comes from the tool used to cut the pieces: a jig saw.

Here's a breakdown of the history:

* Early Puzzles: Before the invention of the jig saw, puzzles were often made by hand, using knives or other tools to cut irregular shapes. These were laborious and time-consuming.

* The Jig Saw: The jig saw, a powered saw with a thin, reciprocating blade, was invented in the 18th century. This allowed for the precise and efficient cutting of intricate shapes, making it ideal for creating puzzles.

* The Name Sticks: The name "jigsaw puzzle" became popular in the 19th century, as these puzzles became increasingly common. The name reflected the primary tool used to make them.

So, while you may not always think of the jig saw when you're working on a puzzle, it's the reason for the name!
