Spiral blades have cutting teeth around the entire periphery of the blade due to their helical shape. This means that they can saw in any direction.

This design allows work to be fed in straight moves - i.e. the workpiece doesn't have to be turned, so sharp inside corners can be created.

Spiral blades also allow you to work on longer workpieces that couldn't be turned on a 16 or 21 inch scroll saw.
