发明名称 Chalk line end fastener
摘要 This Chalk Line End Fastener, is a hook similar in size to the conventional hooks but is cylindrical and narrower, coming to a sharp point. This pointed hook can still be used in the prior art manner, but more effectively can be pushed into most surfaces without the use of additional tools, fasteners, or a helper to hold the end of the line securely in place. The design of the front of the body of this invention allows for maximization of surface area, which eases any pressure on the user's fingers as they push the point into a material to secure the chalk line. The rear of the body is designed to allow the user to lift straight up on the chalk line and easily disengage the point. There is also a lip at the back of the body which allows the user to pry the point straight out.
