How are jigsaw puzzles made?

How can a jigsaw puzzle fit so well together after all the shavings and dust that you find in the box have been lost? Why isn't there a small gap between all the pieces? Some of them fit together so snugly you can pick the entire thing up ... how come?

And back in the sixties I worked for the Victory company in Bournemouth and we cut them on a bobbin machine by hand with very thin 6 inch blades...6 puzzles at a time.Quite often the blades would brake and stick in your hand..blood every where...(:)it took about a month of training to cut them to a profesional finish.

Some puzzles claim to be laser cut.

Some wooden jigsaws are cut using a very high pressure water jet.
