An ergonomic seam ripper includes: (a) an elongated haft with a bulged profile having a larger cross-section about its medial portion than cross-section at a palm end of the haft, the cross-section about the medial portion of the haft also being larger than a cross-section at a thumb grip end of the haft, wherein the palm end of the haft has an outer surface of generally planar structure and the haft is further characterized by a mounting portion at the thumb grip end of the haft; (b) a gripping member secured to the mounting portion of the haft made of a resilient rubbery material with a plurality of gripping ribs extending thereabout, wherein the gripping ribs are spread relatively close together at an upper portion thereof and relatively further apart at a lower portion thereof; and (c) a U-shaped cutting blade with a tapered projection and balled projection, as well as a shaft, wherein the shaft of the blade is secured to the haft such that the tapered projection is aligned with the upper portion of the gripping member and the balled projection is aligned with the lower portion of the gripping member.

Device for delivering gases for extinguishing fire in an enclosed space. The device comes in a spherical shape, the top and bottom of which respectively have an entry hatch. Each entry hatch is held in place by four keyed cam locks. The device includes spiral bevel gears, a stationary ring and four pinions. Each pinion is responsible for containing/releasing the gases stored therein. Each pinion connects to a cylinder that connects to a cone having slits that allow the gasses to travel in different directions. The device is pitched from outside into the enclosed space or burning room. The device allows first responders with either a timed extension to rescue trapped individuals/things or potentially extinguish a burning room. The device withstands structure fires without becoming damaged. The gases contained inside the device are safe to use in areas populated by humans and are both effective and safe for inhalation.

An electrical wire outer coating splitting device featuring an elongated sleeving element, a nearly as long closed hole space within the sleeving element and having a vertically inclined central axis of symmetry and with the notch portion thereof cut into the outer walling of the sleeving element at a bias relative to the lie of the axis of symmetry and with the notch portion thereof being further amenable to removable receipt and dependable holding of the body portion of a seam ripper element.

A stitch ripping assembly for hands free stitch ripping includes a base that is positionable on a support surface. The base is rounded and is elongated along a longitudinal axis such that the base has an ovoid shape. Additionally, the base has a prominence extending upwardly therefrom. A gripping pad is coupled to the base and the gripping pad is comprised of an adhesive material to inhibit the base from sliding on the support surface. A stitch ripper is pivotally coupled to the base. The stitch ripper is positionable to extend upwardly from the base at a plurality of angles. In this way the stitch ripper can rip stitches without being held by a user.

A dual blade retractable tool is provided. The tool has a round tubular housing and a one-piece injection molded slide block structure. The housing has a longitudinally extending control slot and two ends with blade extension openings, one major and one minor. The one-piece structure has a major blade and a minor blade, each carried by a support. Each blade projects through the corresponding blade extension opening. One support is attached to a leaf spring cantilevered at the other end. The spring carries a control button, which projects through and moves within the slot, and a locking pin, which extends beyond the spring perpendicular to the control slot. Depressions in the tube engage and dis-engage with the locking pin as the button is pressed and moved.

A seam ripper includes a metal blade member, a handle and a slider. The blade member is supported by the handle and made of a shaft and a blade part at an end of the shaft. The slider causes the blade member to move between a retracted position and an advanced position. The shaft is housed in the handle at the retracted position. The blade part and at least a portion of the shaft are outside the handle at the advanced position. The blade part includes a cutting blade flanked by a needle portion and a ball-shaped portion. When the blade member is at the retracted position, the entirety of the needle portion is housed in the handle, and a portion of the cutting blade is exposed to the outside of the handle.

A cutting device is disclosed. The cutting device has a housing and a carriage that is movably disposed in the housing, the carriage being movable between a retracted position and an extended position. The cutting device also has a cutting member that is removably disposable in the carriage, a cover member that is removably attachable to the housing, and an urging member that operably connects the carriage and the housing. The housing includes a locking member. When the carriage is in the extended position and the cover member is attached to the housing, the locking member locks the cover member to the housing. The urging member urges the carriage to move from the extended position toward the retracted position.
