Patent ID: 7644502

Claim:
A tool, comprising: an elongated member having a distal indicating portion, the distal indicating portion having a first indicating edge lying along a first axis and a second indicating edge lying along a second axis, the first axis and the second axis defining an indicating line angle, the indicating line angle being bisected by a third axis, the first axis, the second axis, and the third axis being substantially coplanar; and a base coupled to the elongated member, the base having a first reference surface lying in a first plane that is parallel to the first indicating edge, a second reference surface lying in a second plane that is parallel to the second indicating edge, the first plane and the second plane intersecting at a line that is orthogonal to the third axis, a first lip extending from the first reference surface, the first lip defining a first reveal edge, the first reveal edge being parallel to the first indicating edge, and a second lip extending from the second reference surface, the second lip defining a second reveal edge, a distance between the first reveal edge and the first reference plane being the same as a distance between the second reveal edge and the second reference plane, wherein the first indicating edge, the second indicating edge, the first reveal edge, the second reveal edge and the third axis are all substantially coplanar, wherein the position of the elongated member in relation to the base is adjustable along the third axis.
