Abstract
An adjustable reciprocating saw has the ability to adjust the orientation of the saw blade in relation to the rest of the tool. The saw blade can pivot about two transverse axes, one parallel with and one perpendicular to the reciprocating motion axis of the saw blade. The portions of the saw's housing which rotate relative to one another are attached with a rotating joint comprising a pin and groove design. Rotation locks selectively prevent rotation of the saw blade about each axis. The rotation locks can be released through simply depressing buttons on the saw. A rear internal bearing increases the durability and decreases the size of the saw. A keyless adjustable shoe is mounted to the saw.

A reciprocating shaft and bearing combination for a reciprocating saw comprising:
- a bearing mounted to the saw;
- a reciprocating shaft having a blade holder at a first end thereof for holding a saw blade, the reciprocating shaft having a reciprocating motion relative to the bearing defining a reciprocating motion axis, the reciprocating shaft also having a bore formed in a second end opposite the first end, the bore being formed parallel to the reciprocating motion axis and a first end of the bearing being positioned inside the bore;
- a first bearing surface formed on the bearing;
- a second bearing surface formed on the bore;
- and
- wherein the first bearing surface supports the second bearing surface for sliding movement therebetween.
A reciprocating saw comprising:
- a saw blade extending from the saw and having a reciprocating motion;
- a shoe for bearing against a workpiece, the shoe extending from the saw adjacent the saw blade, the shoe mounted to a post slidably received in a bore in the saw;
- a locking mechanism rotatably mounted to the saw for locking the post to the saw, the locking mechanism being rotatable with respect to the saw about a rotational axis, the locking mechanism having at least one protrusion at an axial end thereof extending axially away from the locking mechanism;
- wherein
- in a first rotational position, the at least one protrusion engages a detent in the post so that the post is locked relative to the saw, and in a second rotational position the at least one protrusion does not engage the detent so that the post can slide in the bore relative to the saw blade.
