Claims: What is claimed is:

1. A paralleling tool and gauge for dentists and the like, and providing means for manipulating to a desired position and condition to indicate the desired spacing and offset of teeth, said tool including: (a) a pair of blade members arranged in a scissors relationship with at least one of said blades having a longitudinal slot in and through its midlength; (b) a pivot means holding the two blade members in a near contiguous relationship and with this pivot means extending through the slot and enabling longitudinal movement of one blade with the other, this pivot means retaining the blades so as to be moved only against a determined friction and to the selected attitude and position; (c) a movable end member disposed at one of the ends of each blade, each end member having a support surface by which is placed in a contiguous relationship to a selected end surface of the blade and with the end member having a face surface substantially normal to the mounting surface; (d) a pivot means by and with which each end movable member is pivotally secured to the blade member with said pivot means having a determined friction so that the end member may be selectively moved against said friction to a desired position and condition in which the end members are bent and substantially at right angles and the pivot securing means is a rivet extending through holes in the blade member and end member and securing the movable end member so that the upstanding faces of each of the members are in or may be moved to a common plane; and (e) manipulative on the blades are bent ends formed on each blade so that an attendant may move the several components of the assembled tool to the desired condition.

2. A paralleling tool as in claim 1 in which the tool is made of stainless steel.

3. A paralleling tool as in claim 2 in which the tool is made of stainless steel sheet metal.

4. A paralleling tool as in claim 1 in which the pivot means for securing the two blade members together includes a rivet and a retaining ferrule.

5. A paralleling tool as in claim 1 in which the pivot means for securing the two blade members together includes a rivet and a retaining ferrule.

6. A paralleling tool as in claim 1 in which the blade members at least are made of high strength and temperature resistant plastic such as ABS, LEXAN and the like.

7. A paralleling tool as in claim 6 in which all parts are made of plastic.

8. A paralleling tool as in claim 1 in which only one of the blades has a longitudinal slot and the other blade has a rivet retaining hole formed midway of its length, this hole disposed and sized to retain a through rivet which provides said pivot means.
