摘要:
A circular cutting blade is configured for cutting meat when turned about a rotation axis in a predetermined cutting direction. The cutting blade has a peripheral blade edge defined between the first and second sides and a plurality of circumferentially disposed cutting knives. Each cutting knife includes first and second knife sides and an arcuate knife edge that constitutes a portion of the peripheral blade edge. Each knife edge is titled and rises, relative to the rotation axis, between a first blade-edge location corresponding to a minor blade radius and a second blade-edge location corresponding to a major blade radius such that, when the circular blade is rotating in the predetermined cutting direction and cutting a work piece, the work piece first encounters the first blade-edge location of each cutting knife before encountering the second blade-edge location of that cutting knife.

A fluid sprayer includes a rigid fluid conduit extending along a conduit axis between longitudinally opposed open conduit first and second ends. A spray nozzle having a fluid-expulsion bore is connected to the conduit second end such that the nozzle can pivot about a nozzle-pivot axis that extends orthogonally to the conduit axis and fluid introduced into the conduit first end is expelled through the fluid-expulsion bore. An attachment-mounting arm is connected to the fluid conduit for pivotal movement about an arm-pivot axis having a component of spatial extension orthogonal to the conduit axis and being longitudinally non-displaceable relative to the rigid fluid conduit. Moreover, the attachment-mounting arm is selectively lockable into a plurality of discrete angular positions relative to the conduit and configured to removably retain a surface-engaging attachment designed for engaging a surface to be cleaned.

A liquid loading and application apparatus includes a hub, a paint roller support element, and the hub receives the paint roller support element. The hub includes first and second frusto-conical surfaces subtending an angle, and oppositely disposed annular end surfaces contiguous with the respective first and second frusto-conical surfaces. A cover of a first material conforms to the frusto-conical surfaces. The cover has opposed circular openings, and elastic strips of a second material. The elastic strips engage the frusto-conical surfaces and grippingly secure the cover to the hub. The first material is more elastic than the second material so that the strips grippingly secure the cover to the hub.

Each knife edge rises, relative to the rotation axis, between a first blade-edge location corresponding to a minor blade radius and a second blade-edge location corresponding to a major blade radius and further includes beveled primary and secondary knife-edge portions along which the first and second knife sides mutually converge at, respectively, a first bevel angle and a second bevel angle less acute than the first bevel angle.

A sponge sander configured for selective attachment to a dust-collection system includes a housing having a housing-interior surface defining a sponge cavity and a sponge seat configured for removably retaining a determinately-dimensioned sanding sponge. The sponge has an abrasive sanding surface, a back surface opposite the sanding surface and a sponge periphery defined between the sanding and back surfaces. The sponge is retained within the sponge cavity such that (i) the abrasive sanding surface can engage a work surface to be sanded, (ii) fluid-flow channels are maintained between the sanding sponge and the housing-interior surface and (iii) the spaces are in fluid communication with a fluid port defined in the housing so that when a negative pressure is applied across the fluid port by a vacuum system external to the housing, dust created by sanding is drawn into the fluid-flow channels and out of the housing through the fluid port.

A knife includes a handle body defining an interior blade-slide cavity housing a blade slide carrying a blade with a cutting edge. The blade slide is reciprocated within the blade-slide cavity between a blade-storage position in which the cutting edge is housed within the handle body and at least two blade-protruding positions in which the cutting edge protrudes to the exterior of the handle body, through a forward-end opening, to disparate extents. Blade-slide reciprocation is facilitated by a blade-slide actuator that includes a button reciprocable along an actuator slot defined through the handle body. A handle-body undulated surface defined along the handle body in the vicinity of the actuator slot is configured for selective mechanical interference with a button undulated surface in order to define the at least two blade-protruding positions. A blade-protruding position is temporarily maintained through a user's depression of the button to maintain the selective interference.
