A saw blade for use with a reciprocating saw includes a body and an attachment portion extending from the body. The attachment portion includes a tang and an aperture configured to connect to the reciprocating saw. The saw blade also includes a cutting portion formed on the body. The cutting portion includes a plurality of cutting teeth, and first and second floor guard teeth spaced apart and positioned adjacent at least one of the plurality of cutting teeth. Each cutting tooth has a tip that defines a plane. The body has a first height measured generally perpendicularly from a back edge of the body to the plane. The attachment portion has a second height measured generally perpendicular to the plane. A ratio of the first height to the second height is between approximately 4 and approximately 5. The first and second floor guard teeth extend beyond the plane.

A ring cutter for removing an ornamental ring encircling a person's finger is disclosed. The ring cutter includes an oscillating hand-held multi-tool with a blade substantially oriented at a right angle that oscillates to cut the ring. The oscillating blade has an oscillating amplitude small enough to avoid any injury to the finger. The ring cutter further includes a tissue depressor and guard attached to the head portion of the ring cutter and functions to push down the swollen tissues that surround the ring that need to be cut and help in avoiding finger injury. The ring cutter further includes a sprayer assembly to deliver a jet of cooling liquid (such as water) to cool down the ring and blade and prevent any thermal burn during the cutting operation.

A saw blade for use with a power tool includes a body with a first planar surface and a second planar surface opposite the first planar surface. The saw blade also includes an attachment portion that is configured to couple to the power tool. The attachment portion includes a tang and an aperture. The saw blade further includes a cutting edge with a plurality of cutting teeth and a plurality of hexagons formed on the first planar surface. The plurality of hexagons are arranged in a honeycomb pattern in which at least one side of each hexagon is substantially parallel to a corresponding side of an adjacent hexagon.

Apparatus for converting rotary motion to linear motion and/or linear motion to rotary motion, comprising: a rotatable piece (24) having a surface, the piece being rotatable about an axis thereof; at least one member (26a-d) having a linking surface (44a-d) facing the surface of the rotatable piece and arranged for restricted movement at least in part laterally relative to the axis of the piece; and located between the surface of the rotatable piece and the or each reciprocating member, means for linking the linking surface of the respective member and the surface of the rotatable piece, wherein the means for linking (30a-d), the surface of the rotatable piece and the linking surface are configured to cooperate so that rotational motion of the rotatable piece causes linear movement of the at least one member, and/or linear movement of the at least one member causes rotational motion of the rotatable piece. A sawing device may include said apparatus, the sawing device being for cutting by repetitive reciprocating cutting action of at least one blade on a surface of an object to be cut. A saw blade (10a-d) may be configured for such a sawing device.
