I'm pretty sure the only requirement is that it's been cut by a jigsaw
My mum had one which was all yellow called 'flat banana'.
I guess some people enjoy that kind of thing.

The type of saw involved shouldn't detract from the puzzle making
maybe someone should start a company called jigsaw, kind of like how there's a company here called '100% australian beef' which means mcdonalds can say they have 100% australian beef burgers.
