The present disclosure relates to a hand-held machine tool. The hand-held machine tool includes: a first moving component as a main vibration source, the first moving component reciprocating substantially in a straight line in a first direction; a second moving component as a secondary vibration source, the second moving component having a movement state different from that of the first moving component; and a balancing block, with a linear movement direction of the balancing block being a second direction in a different plane from that of the first direction, and a movement pace of the balancing block being opposite to that of the first moving component.

A reciprocating saw blade that includes an elongated blade body defining an inner end and a distal end, a cutting edge located on one side of the blade body and extending between the inner and distal ends thereof and a tang located at the inner end of the blade body. The tang projects from the blade body at an acute angle of at least about 3 relative to a line tangent to an inner end of the cutting edge. The cutting edge includes a portion defining a substantially curved contour and optionally can include at least one further portion defining a non-curved contour.

A power tool includes a housing and a hook assembly. The hook assembly includes a hook support and a hook member. The hook support is rotatably attached to the housing for rotation about a first axis. The hook member has a shank portion and a hook portion. The shank portion defines a second axis that is transverse to the first axis and is configured to rotate with respect to the hook support about the second axis.

A reciprocating drive mechanism for a power tool includes a rotatably mounted transmission shaft that has a first central axis, a spindle with a spindle body, and a counterweight for linearly reciprocating motion under the guide of at least one guiding rod. A wobble plate is mounted on the transmission shaft and includes a first arm and second arms extending in opposite directions. The first arm and second arms are configured to cooperate with the spindle and the counterweight respectively so that, upon rotation of the transmission shaft, the first and second arms of the wobble plate drive the spindle and the counterweight to reciprocate in opposite directions parallel to the second central axis. An angle is formed between the extending direction of the first arm and the second arm and a plane defined by the first central axis and the second central axis.
