Black and Decker say: "Think of a handsaw without the hard work. From fence posts to drain pipes , floorboards to worktops the Scorpion powered handsaw gives you a fast clean cut in seconds. The large capacity cutting area delivers great results without the effort and in a fraction of the time it would take with a conventional handsaw."
The saw is more than a reciprocating saw - it's also a jigsaw, although most owners don't use that function
One questioner asks if the saw will cut through a railway sleeper - probably not! However, Scorpion dedicated metal cutting blades allow you to cut all types of Non Ferrous metal and even light gauge sheet steel,
One female user has had the saw for three years and has managed to replace a snapped blade herself, so it's fairly easy to maintain.
Another woman says "Being a woman living on my own I need to do everything myself, I am always doing something and having the right tools makes the job easier."
