An oscillating power tool includes a drive motor (M) producing rotary motion and an oscillating mechanism (30) for converting the motor rotary motion to an oscillatory side-to-side movement. The oscillating mechanism (30) includes a link (32) driven by an eccentric shaft (16) of the motor (M), a drive arm (40) that drives the hub (45) of the working tool (B) in oscillating motion, and a bearing arrangement (37) between the drive arm (40) and the link (32) that isolates relative rotation and translation between the components while still imparting an oscillatory motion to the drive arm (40).

A method and a hand-held device for dermaplaning is disclosed that includes a blade assembly which includes a blade, a blade holder and a safety cage. In accordance with an important aspect of the invention, the safety cage limits the amount of penetration of the blade into the facial skin to enable the device to be safely used by non-professionals. The dermaplaning device includes a vibration generator that causes the blade to vibrate at a predetermined frequency. Various embodiments of the hand-held dermaplaning device are disclosed for vibrating the blade.

A method for attaching a first object to one or more second objects of dissimilar materials, without any bonding material, using a molded attachment block is provided. Anchoring grooves are created and a constrained assembly is positioned at opposing sections on a surface of the first object. A tension is generated in tension bearing members anchored in the anchoring grooves and extended along a length of the constrained assembly. The constrained assembly is constricted between mold side members positioned perpendicular to the mold end members. The tension bearing members are clamped between bolt assemblies. A viscous liquid is poured and cured on the constrained assembly, the tension bearing members, the anchoring grooves, and the bolt assemblies for creating the molded attachment block with opposing ends of the threaded members of the constrained assembly extending outwardly from the molded attachment block for attachment to second objects without any bonding material.

An accessory tool for an oscillating power tool includes a mounting portion, and a blade portion that extends from the mounting portion. The blade portion includes a first lateral edge portion, a second lateral edge portion, and a leading edge portion. A cutting edge is defined in the second lateral edge portion that includes a rearward facing portion that extends generally laterally from a distal end portion of the second lateral edge portion toward the first lateral edge portion and a forward facing cutting edge portion that extends from said second lateral edge portion toward said first lateral edge portion. The rearward facing cutting edge portion is at least partially interposed between the leading edge portion and the mounting portion, and the forward facing cutting edge portion is at least partially interposed between the rearward facing cutting edge portion and the mounting portion.

A winder unit for winding cutting line, for vehicle glazing panel removal, has a rotatable spindle shaft for winding the cutting line and a ratchet device mounted to the spindle shaft by means of a one-way rotational bearing or clutch. Typically the ratchet device has a component mounted to rotate in unison with the one-way rotational bearing or clutch. The improvement provides a rotational directional control providing 2 one-way rotational control devices in concert.

An accessory tool for an oscillating tool includes a first metal plate and a second metal plate fixed together to form a body having a first end portion formed by the first metal plate and a second end portion formed by the second metal plate. The first end portion defines a linear cutting edge, and the second end portion defines a drive interface for mounting the accessory tool onto a tool holder of an oscillating tool. The second metal plate includes an overlapping portion that overlaps a portion of the first metal plate. At least one of a first lateral portion and a second lateral portion of a leading edge of the overlapping portion is spaced farther away from the cutting edge than a central portion of the leading edge of the overlapping portion.
