Abstract: A pointed tool and sheath combination allow for use of the tool as a string line anchor and/or as a plumb bob and provide safe storage of the tool when not in use. The preferred tool is comprised of a dart-like body having a longitudinal axial bore, and a sharpened spike clamped within the longitudinal bore. Sheaths are provided that with snap-in installation of the tool down past curved, inwardly-protruding walls of the sheath, or of the tool into engagement with a latching arm that cooperates with a recess or other latching surface on the tool.

Abstract: This invention is a tool combining the function of a string line or chalk line anchor and a plumb bob. This combined tool is comprised of a dart-like body having a longitudinal axial bore. A sharpened spike is clamped within the longitudinal bore. The amount of the spike extending from the body may be adjusted to accommodate the variety of material hardnesses encountered at the work site. In addition this tool has the added functionally of being able to easily and quickly replace a damaged or broken spike.

Abstract: Embodiments of a sheath for a pointed tool are described, which tool may be a combination string/chalk line anchor and plumb bob. The sheath includes a cavity for housing the pointed needle or spike that extends out from the combination tool, and a cavity for at least partially encircling the body of the tool. A locking mechanism is included to secure the tool in the sheath until removed is desired. The sheath may include a system for attaching it to a chalk box, and a slot defining an exit-point for string line to extend out from the sheath to the chalk box or other container or spool.

Abstract: A tool is disclosed which incorporates both a stick-pin peg and an eyelet-shaped hook, either of which may be used to anchor a chalk line. The tool can also double as a plumb bob. The tool has a peg-shaped body with a longitudinal axis. The body has a tapered lower end which terminates in a sharpened stick pin. The body has a recess for holding the eyelet-shaped hook and also incorporates a clamping mechanism which both releaseably secures the hook within the recess, and eliminates any need for tying and untying the string to the tool. The string remains secured to the eyelet-shaped hook. In order to secure the line with the eyelet-shaped hook, the hook is removed from the body by releasing the clamping mechanism. In order to secure the line with the stick-pin peg, the eyelet-shaped hook is secured within the body recess and the string is secured to the needle point by looping the string over itself twice. In order to utilize the anchor/bob as a plumb bob, the body is suspended from its longitudinal axis.
