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 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 skiver for precise removal of outside material from an elongated device, such as a medical catheter or the like, includes a longitudinal recess in a surface and a transverse replaceable blade therein. A removable cover holds the blade in place. In some embodiments, the skiver has a handle extending from the skiver. In other embodiments, an automated mechanism is used to move the elongated device through the skiver.

Existing blade assemblies for cutting complex three-dimensional shapes such as twisted shapes are typically slow and suffer from frequent breakdowns. Disclosed herein is a stationary blade assembly for cutting food products into complex shapes as the food products are directed along a direction of flow at the blade assembly, wherein the blade assembly comprises a plurality of blades, each of the plurality of blades having a length, wherein the length of the blade is oriented along the direction of flow and the blade is twisted along its length, whereby the food products are rotated by the blade during cutting.

Herein described is a cutting method for closure of the tethered type, wherein a spindle which carries a closure is moved towards a cutting device with one or more horizontal blades and at least one vertical or oblique blade. When cutting, the spindle rotates and the closure rolls on the cutting device. The spindle, which is fed several times to the cutting device each time carrying a different closure comprising a portion made of a material softer than the blades, therefore when cutting the blades penetrate into the closure material and therefore sink into the softer portion of the spindle. The spindle feed which carries the closure towards the cutting device is coordinated with the rotation of the spindle so that the vertical or oblique blade, each time the spindle is fed to the cutting device, always encounters the same area of the softer portion of the spindle. The method provides for a preliminary step in which the blades are moved in such a way as to gradually increase the depth with which they sink into the soft portion starting from an initial position distant from a nominal working position and reaching a final position in which the blades sink into the soft portion with a greater depth than the depth with which they sink when they are in the nominal working position.

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.
