1. Field of the Invention
This invention relates to the field of hand tools. More specifically, the invention comprises a finger guide which assists a user in measuring, cutting, marking, and scoring objects such as lumber, plywood, and sheetrock.
2. Description of the Related Art
Numerous marking and cutting guides are used in the construction industry. Tape measures are employed to measure distances. Framing squares provide perpendicular markings for transverse cuts. Large saw guides are used for cutting straight lines over large distances (such as “rip” cuts along the length of a board). These devices tend to be fairly large, making them difficult to carry around the work site.
Additionally, many of the prior art devices require the user to run his or her fingers along the edge of the object to be cut. This operation is not difficult, but when it is repeated many times throughout a work day it produces skin abrasions. Splinters and reinforcing fibers may also be lodged in the user's hand.
The present invention comprises a finger guide for use in measuring, marking, scribing, cutting and similar operations common to the field of construction. The device assists in performing these operations on an object such as a board or piece of drywall. The finger guide has a top guide which is laid on the top surface of an object, and a perpendicular edge guide which abuts an edge of the object. The edge guide includes an index finger hole which allows the user to slip the device on his or her index finger and “wear” it like a ring. The top guide opens into a tape trough positioned to receive and hold a length of metal tape from a conventional tape measure. The top guide also includes reference marks used for measuring. Other features allow the device to be used as a saw guide in conjunction with a conventional circular saw.

Edge guide 14 opens into index finger hole 20, which passes transversely therethrough. Edge guide 14 also contains a second surface distal to edge mating surface 24. This second surface includes middle finger trough 21, the purpose of which will be explained subsequently. Edge guide 14 also contains relief bevel 26 and fillet 28. These features allow finger guide 10 to pass by obstructions in use.
A first use of finger guide 10 is the measurement of board widths.
Finger guide 10 is thus worn like a ring, with the interface between the middle finger and middle finger trough 21 providing a stable orientation for finger guide 10 without the user having to tightly grip it. The user's thumb 46 is used to press tape 38 firmly down into tape trough 16.
