In one embodiment, a method includes causing a robotic limb to intercouple with a handle of a knife. The knife comprising a handle at a proximal end where the handle is configured to intercouple with the robotic limb, a bade connected to the handle, and an indentation at a distal end where the indentation is configured to intercouple with a bar of the cutting surface, and where the blade is rotatable around a first axis while intercoupled with the bar. The method includes causing the indentation of the knife to be intercoupled with the bar of a cutting board. The cutting board comprising the cutting surface and the bar affixed to the cutting surface. The method includes adjusting, by the robotic limb the position of the knife along the bar to along with an object on the cutting surface and rotating the knife to cut the object.

A power tool includes a spindle, a motor, an inner housing and an outer housing elastically connected to the inner housing. The inner housing is formed by a first inner housing portion formed of metal connected to a second inner housing portion formed of synthetic polymer. The first inner housing portion includes a housing part disposed in a front part of the outer housing, and a first extending part extending rearward from the housing part and disposed in a grip part of the outer housing. The second inner housing portion includes a second extending part that has a tubular shape and at least partially surrounds the first extending part, and a rear end part connected to the second extending part and disposed in a rear part of the outer housing. The first extending part extends rearward of a center of the second extending part in the front-rear direction.

A power tool includes a housing, a spindle, a clamp shaft, a first biasing member, an engagement member, a first holding member, a manually operable member and a push-down member. The first biasing member biases the clamp shaft upward. The first holding member holds the engagement member to be movable between a first position and a second position in the up-down direction relative to the first holding member. The manually operable member moves a first one of the engagement member and the first holding member downward in response to a manual unclamping operation. The engagement member moves from the first position to the second position to be movable in the radial direction in response to the manual unclamping operation. The first one of the engagement member and the first holding member pushes down a tool accessory via the push-down member while the first one is moving downward.

A blade assembly includes a blade support frame, and a plurality of V-shaped blades removably fastened to the blade support frame. The blade support frame has a food flow path extending downstream, and a plurality of blade mounts distributed around the food flow path. Each V-shaped blade has a first end portion connected to one of the blade mounts, a second end portion connected to another of the blade mounts, and an intermediate portion extending from the first end portion to the second end portion into the food flow path. At the first and second end portions of each V-shaped blade, a respective one of the blade mounts overlies both the upstream edge and the downstream edge of the V-shaped blade to inhibit the V-shaped blade from rotating when impacted by food.

A power tool, such as an oscillating multi-tool, is configured to drive a tool accessory in an oscillating manner. The power tool includes a motor, and a spindle supported to be rotatable around a driving axis and configured to pivotally oscillate the tool accessory, which is removably mounted on the spindle, using power generated by the motor. An inner housing of the power tool houses the motor and the spindle, and has at least one airflow inlet and at least one airflow outlet. An outer housing of the power tool houses the inner housing and is elastically connected to the inner housing via at least one elastic member to be movable relative to the inner housing. A partition is disposed between the at least one inlet and the at least one outlet. The partition divides a space defined between the inner and outer housings into first and second airflow spaces.

A cutting apparatus and a cutting device are disclosed including a modular insert arranged at least partially in a housing cavity, in which the modular insert includes a cutting element for performing a vertical or oblique cut and an abutting block which is interchangeable and couplable with the cutting element to fix a total dimension of the modular insert, in which an abutting face of the abutting block abuts on a back wall of the housing cavity so that a rear end of the cutting element is spaced away from the back wall. An assembly method is disclosed for assembling the aforesaid device including the steps of providing a plurality of interchangeable abutting blocks and of choosing an abutting block between the plurality of interchangeable abutting blocks on the basis of a desired total dimension of the modular insert.
