Some tools do only one thing well. Some tools do a lot of things well if you know how to use them. The jigsaw (or sabersaw), in my opinion, is unique in the pantheon of modern woodworking tools as it does nearly everything with equal parts of ineptness and frustration. So why keep it around? It’s the only portable tool that cuts curves. And that makes it invaluable in the shop when the project calls for it.
