A method and apparatus for manufacturing an embossed sanding sponge includes a first roller, a press base, and a conveyor. The first roller is mounted about an axis and configured to be rotatably driven about the axis. The first roller also includes a circumferential surface having a predetermined channel pattern. The press base is positioned proximate to the first roller and configured to compress the sponge material against the first roller. The conveyor has a support surface configured to translate and support the sponge material. In use, the circumferential surface of the roller engages the sponge material. The roller and the sponge material respectively rotate and translate in order to continuously press the predetermined channel pattern against the sponge material for manufacturing the embossed sanding sponge.

A blocking tool and a method of using the blocking tool to sand a surface of a vehicle are disclosed. The blocking tool includes a first member having a length and having an outer periphery with a plurality of cuts formed therein. The plurality of cuts extend over at least about 70% of the length and each of the cuts penetrates the first member through an arc of at least about 70% of the outer periphery. The blocking tool also has a base member with a first surface, an oppositely aligned second surface, and a length. A portion of the outer periphery of the first member is secured to the first surface of the base member to form an integral blocking tool.

Apparatus and method for sharpening a cutting tool, such as but not limited to a knife. A sharpener has a housing with a sharpener stage adapted to facilitate a sharpening operation upon the cutting tool responsive to retraction, by a user, of the cutting tool along a longitudinal drawing axis. A tiltable sharpening mechanism is disposed within the housing adjacent the sharpening stage. The tiltable sharpening mechanism has a central body that is rotatable about a transverse rotational axis nominally orthogonal to the longitudinal drawing axis. The rotatable central body supports at least a first sharpening element. In some cases, the central body supports a pair of intersecting sharpening elements. A biasing member exerts a biasing force to urge the central body of the tiltable sharpening mechanism to a neutral position within the housing. The central body can be locked in neutral, positive rake and negative rake positions.

Object: Providing a polishing pad that is deformable with a smaller force. Solution: A polishing pad (1) according to an aspect of the invention includes a substrate (2) made of a piece of non-woven fabric. The substrate (2) has a flat-plate shape extending in a first direction perpendicular to a thickness direction and in a second direction perpendicular to both the thickness direction and the first direction. The substrate (2) is divided into a plurality of blocks (3) arranged in the second direction and each extending in the first direction. A boundary portion (4) extending in the first direction is formed between each pair of the blocks (3), and a plurality of slits (6) are formed in the boundary portion (4). Each of the slits (6) is formed through the substrate (2) in the thickness direction and extends in first direction. The plurality of slits (6) that exist in the boundary portion (4) are spaced apart from each other in the first direction. A pair of the blocks (3) that are next to each other in the second direction are connected to each other by a connection portion (7) formed between the slits (6).
