A reversible, multiple-bit, hand tool for driving threaded fasteners and nuts includes a handle and a reversible tool holder assembly. The reversible tool holder assembly is insertable into the handle in either of two orientations to present two different ends provide multiple different configurations for driving different types of threaded fasteners and nuts. The reversible tool holder assembly includes a reversible adapter barrel, a first tool holder, a second tool holder, a first reversible bit holder, and a second reversible bit holder. Each of the tool holders can be selectively used as a nut driver with the holder assembly inserted in either orientation in the handle or can be removed from the adapter barrel and used separately as a power bit driver or a power nut driver (PND) that is received in any conventional chuck of a powered rotary tool.

A tool includes a first body, a rotary member, a positioning unit and an engaging unit. By the positioning unit and the engaging unit, the rotary member is positioned relative to the first body with dual-positioning feature. When the first body is rotated, the rotary member is positioned by the positioning unit and the engaging unit. The rotary member is not likely to freely rotate because both of the positioning unit and the engaging unit fail when using the tool.

A workpiece engaging surface that includes a pattern of laser-etched channels and related method of manufacturing is provided. The laser-etched pattern on the surface of the workpiece engaging surface is formed by multiple groupings of closely spaced channels that generate serrated teeth in the surface of the tip. Each grouping of channels is formed by passing a laser over a first location a first number of passes to form a first channel, passing a laser over a second location, spaced apart from the first location by a channel spacing distance, a second number of passes to form a second channel, and passing a laser over a third location, spaced apart from the second location by the channel spacing distance, a third number of passes to form a third channel. In some embodiments the first, second, and third number of passes are the same.

A wallet includes a first shell with one or more openings on a shell perimeter adapted to clip one or more objects to the one or more openings; and a second shell coupled to the first shell, the second shell including a storage compartment; and first and second rails on each side of the second metal shell to slideably receive one or more cards in the storage compartment.

The present invention discloses a method for manufacturing a screwdriver head, the screwdriver head including a head portion for being inserted into a slot of a screw head and a basal body for supporting the head portion; the manufacturing method including: providing the screwdriver head made of a first metal material; preparing alloying coating; coating the alloying coating on the surface of the head portion of the screwdriver head; conducting laser surface alloying treatment on the surface of the head portion coated with the alloying coating to form an alloyed layer; and conducting low temperature tempering treatment on the screwdriver head after the laser surface alloying treatment. The present invention further discloses a screwdriver head, the surface of the position at which the head portion of the screwdriver head contacts with the slot of the screw head is provided with an alloyed layer formed through the laser surface alloying treatment. The screwdriver head manufactured by the manufacturing method of the present invention has high rigidity and high abrasive resistance in the head portion and high tenacity in other portions, thereby prolonging the service life.

A fastener and a specialized driver for use in furniture or shelving assembly where the fastener comprises a fastener head with an aperture centered therein and a fastener body extending from connection with the fastener head, the fastener body having an interior cavity along a length of the fastener body. A spring biased plunger is slidable within an interior cavity of the fastener body between a first position where the plunger has a surface configured to fit within the aperture and in a second position the plunger is spaced apart from the aperture. The driver is removably couplable to the fastener to depress the plunger and transfer torque to the fastener for installation. After installation, the plunger resumes a position plugging the aperture and the tolerance between the plunger and the aperture is sufficiently tight to effectively obscure any seam between the plunger and the aperture such that the fastener head surface appears continuous.

A wallet includes a first shell with one or more openings on a shell perimeter adapted to clip one or more objects to the one or more openings; and a second shell coupled to the first shell, the second shell including a storage compartment; and first and second rails on each side of the second metal shell to slideably receive one or more cards in the storage compartment.

A spigot stop removal bit device facilitates removal of a buried spigot stop without having to dig. The device includes a first bit and a second bit each having a respective first end configured for coupling to a driving tool to be selectively rotated by the driving tool. A second end of the first bit is flat. A second end of the second bit is sharpened wherein the second end of the second bit is configured for engaging and cutting into the plug wherein the plug is structurally compromised to facilitate removal of remnants of the plug from the hydrant pipe. Respective lengths of the first bit and the second bit are extended such that the second end of each is configured for engaging a plug positioned in a hydrant pipe.

A belt buckle adapted for securing a plurality of tools. The multi-purpose belt buckle system includes a first component for screwing a screw and a second component for holding the first component. The first component is T-shaped and includes various types of screwdriver heads. The second component further includes a slot for holding the first component, at least one open wrench and least one means for connecting a strap/lace.

A tool bit includes a drive portion configured to be engaged by a tool, the drive portion including a first maximum outer dimension, a shank extending from the drive portion and including a reduced outer diameter, and a tip coupled to an end of the shank opposite from the drive portion. The tip includes a compressive residual stress layer formed by blasting to increase a wear resistance of the tip relative to the shank. The tip additionally includes a second maximum outer dimension. The reduced outer diameter of the shank is smaller than the first maximum outer dimension of the drive portion and the second maximum outer dimension of the tip.
