This can be very useful and money saving for those who like scroll sawing.
It is a sanding blade you install in place of a cutting blade on the saw.
You need to reduce the speed to get efficiency.
It's made of a thin strip of metal sheet, the length of a regular blade, slightly larger, and a sand paper strip stuck on it using double sided tape.
Two little holes at each side, with small pins crossing the holes allow to use them as pin end blades.
