An example combination tool for marking, measuring, and checking level includes a holder for a marking device (e.g., a soapstone). The holder has a body formed by a first side, a second side, a front side, a back side a top side, and a flat bottom side. A securement releasably secures the marking device at least partially within the body. Turning the securement in a first direction tightens the marking device within the body of the holder. Turning the securement in a second direction loosens the marking device in the body of the holder so that the marking device slides in and out through an opening formed in the front side of the body to adjust a position of the marking device for use in marking. The example combination tool may also include measuring markings, a level, a clip, and a grip.

A description is given of a wood-encased pencil comprising a casing and a core, the casing consisting of wood material impregnated with a saccharide component, the saccharide component comprising at least one mono-, di- or oligosaccharide and at least one polybasic organic acid in solution in a vehicle.

A method for releasing impurities from a calcium-based mineral is described. The method comprises reacting a calcium-based mineral containing impurities with an aqueous solution of one or more ionic salts at a temperature of approximately 85° C. or above, wherein at least one of the calcium-based mineral and the one or more ionic salts comprises sulphate and at least one of the calcium-based mineral and the one or more ionic salts comprises ammonium, and wherein the concentration of the solution is approximately 25% or higher mass fraction, such that double salt crystals are formed and impurities are released. The method further comprises separating the double salt crystals from the impurities. Various products of the process are also described.

A writing utensil container formed from a single plastic mold, including a container front panel, a front bottom component, a container back panel, a back bottom component, and a container lid component. A bottom integral hinge component may pivotally couple the back bottom component and the front bottom component, allowing the container front and back panels to pivot toward and away from each other. A lid integral hinge component may pivotally couple to the container back panel with the container lid component for opening and closing thereof. The container front and back panels may have coupling mechanisms that selectively engage with each other to prevent pivoting about the bottom integral hinge component to retain crayon boxes between the container front and back panels. A front closure feature of the front panel may selectively engage with a lid closure feature for selectively retaining the container lid component in a closed position.

A writing instrument for primary use within carpentry a body that extends from a distal end to a proximal end having a marking tip. The body has a substantially round cross-sectional shape and the marking tip is offset from a center of the cross-sectional shape. The round shape can non-uniform, such as ovular or egg-shaped with the marking tip offset from the center of at least the length or the width thereof. The offset positioning of the marking tip relative to the outer surface of the body provides clearance to scribe a building material.

A collapsible dual screwdriver assembly pliers or drive-pliers for short, comprises a pliers and two screwdriver assemblies, where the screwdriver assemblies are individually removably attachable in a stowed position and an extended position. In the stowed position each screwdriver assembly can provide compact storage of the tool as well as function as a portion of a handle for the other screwdriver assembly. In the extended position each screwdriver assembly can be used as an extended handle for the pliers, as well as, function as a multi-bit screwdriver individually.

Devices, kits, and methods for making a carved crayon are provided. In one aspect, a crayon carving device includes a base, a pantograph armature coupled to the base, a crayon positioner, and at least one guide template parallel to the crayon positioner. The kit may further include a wrapper removal mechanism configured to remove a wrapper from a crayon, such that the crayon carving device may be used on an exposed crayon surface.

A wax-based coloring crayon for a porous surface and for a non-porous surface includes at least one wax, an ethoxylated fatty alcohol, stearin, a filler, at least one pigment, and optionally an additive.

A system that aesthetically dispenses melted wax includes a plurality of elongated heating cases, a plurality of wax cartridges, and a plurality of transfer canisters. The plurality of elongated heating cases is used to heat up wax or similar crayon material which is placed inside of the plurality of wax cartridges. The plurality of wax cartridges is used to hold wax or similar crayon material. The plurality of transfer canisters is used to store the plurality of wax cartridges when not in use and to transfer a wax cartridge from the plurality of wax cartridges into an elongated heating case of the plurality of elongated heating cases.
