Black & Decker model BDEJS600 jig/saber saw with Curve Control knob on side of the body to allow better and smoother cutting of curves. They are limited to swooping curves rather than small diameter holes that would probably be better done with drill bits or hole saws. I have included a few saw blades to make it ready to go. The saw has been tested and works as it should. The original price of this saw new was about $70 and when they went on sale they were usually $50 or more.
