The CJS1801K was an 18V cordless jigsaw from Ryobi’s earlier ONE+ generation, sold as a kit with a battery and charger.
It is discontinued. ONE+ batteries remain cross-compatible, so a current pack will run it and your old packs will run a current tool.
What to check on an old jigsaw
The blade guide roller. This is the small wheel behind the blade that stops it deflecting backwards. Worn, it lets the blade flex and the cut goes out of square — which people usually blame on the blade.
The shoe. If it is loose at the bevel adjustment, or no longer sits flat, every cut inherits the error.
The blade clamp. A clamp that lets the blade creep down under load is the end of a jigsaw’s useful life.
Why the current one is better
The Ryobi ONE+ HP brushless jigsaw, linked below, replaces it on the same battery platform.
The brushless motor is not the main gain here. The main gain is blade guidance and orbital action quality: modern jigsaws at this price hold the blade squarer and offer usable orbital settings, which is the difference between a tool for rough cuts and one you would use on a visible edge.
The thing that matters more than the saw
Blades. A jigsaw with a cheap universal blade cuts badly no matter what it cost. Buy T-shank blades matched to the material — a down-cut blade for laminate and veneered ply so the top face stays clean, a coarse fast blade for rough timber, a fine blade for tight curves.
Changing blade type does more for cut quality than changing saw.
