A smoothing tool (10) has a grip part (22) and a blade part (12) accommodated therein, wherein the grip part (22) is formed as a light metal hollow profile and has two brackets (24) clasping the blade part (12), and the blade part (12) has at least one support rib (18) and one or two clamping ribs (14) at least partially clasping a respective one of the brackets (24) of the grip part (22).

A process for manufacturing the composite smoothing tool comprises providing the blade part as a tailored cold drawn steel part.

A dual cell fabric (98), also referred to as a cell-in-cell fabric, comprising a plurality of concentric dual cells (96) that are connected to an adjacent cell along a top and bottom side. Each dual cell of the fabric is made of a flexible material such as a fabric material that is transversely collapsible but retains its configuration along its length when suspended between the head rail (92) and the bottom rail (94). The dual cells consist of an outer cell (100) having pleated front and edges (100a) and (100b) respectively and a smaller concentric cell (102) having corresponding front and rear pleated edges (102a) and (102b), respectively, spaced inwardly from the front and rear edge of the outer cell. Both the inner and outer cells are symmetric about a horizontal plane intersecting a central longitudinal axis of the cells as well as about a similar vertical plane.

A hand-held electric sealer with a detachable sealing module includes a casing (1), a sealing module (3), and a press bar (4). The casing (1) includes, among others, a front contact holder (12) which is provided with an engagement hole (121). The sealing module (3) includes, among others, a lower cover (31) from underside of which extended an engagement piece (312). The engagement piece (312) of the sealing module (3) can be engaged with the engagement hole (121) of the casing (1), such that the sealing module (3) can be conveniently attached to, or detached from, the casing (1), and that replacement of a damaged sealing module (3) can be readily achieved. In addition, for the sealing module (3) dual heating wires (521) may also be employed so as to obtain a desirable sealing effect to plastic bags.

A plastic bottle cutting implement for reducing a plastic bottle such as a PET bottle to an easily compactible form for disposal comprises a cylindrical or part-cylindrical covering member (1) and a blade (3) disposed projecting from the inside surface of this covering member (1), and the direction in which the blade (3) projects has any angle other than perpendicular and parallel with respect to the imaginary centre axis of the cylindrical covering member. A grip part (2) is attached to the outer side of the covering member (1). the grip part (2) is bar-shaped and is attached projecting from the outer side of the covering member (1), a hollow part connecting with the inside of the covering member (1) is formed inside the grip part (2) and a sliding fitting slidable inside the hollow part and fixable in any position inside the hollow part and a blade (3) having one end thereof attached to the sliding fitting are disposed inside this hollow part. The cutting direction of the blade (3) intersects diagonally with a plane orthogonal to the imaginary centre axis of the covering member (1).

A hand-held device for severing flexible polymeric tube, pipe, or tubular extrudate, especially flexible light pipe, reproducibly and cleanly is described. The device comprises a block (14) with holes (20) or openings for holding the pipe and a slit for guiding the severing blade with minimum deviation from its path. An improved design employs a pivot in the block upon which a notched blade in a holder (12) may be mounted to give even more accurate and uniform control of the severing process.
