Abstract: A chalk line is marked by attaching two hooks to a nail, and then extending a string a length from the nail. The hooks are attached to an apparatus that has multiple springs, such that there is a string attached to the rear of the apparatus while the hooks are attached to the front of the apparatus. When the string has been extended the desired length, the user then snaps the line to make a chalk line. Then, the pull on the string is released by the user, causing the two hooks to separate. When the two hooks separate, their connection to the nail is broken. The hooks and the apparatus associated with the hooks then is free to be reeled back to the user. The user does not have to return to the nail to remove the hooks and the associated apparatus.

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.
