Abstract
A Tool for making controlled cuts using a template cutting guide to facilitate the registration and cutting of a workpiece including, an elongated body portion having a top face and a bottom face separated by a thickness, a cutting guide slot sized to receive and control a cutting blade and extending through the thickness of the elongated body which may include guide lines with equidistant spacing. Additionally, the cutting guide may utilize push pins or fasteners to secure the cutting guide to the workpiece. The cutting guide allows the user to execute precise cuts in material such as mat board using a standard utility knife.

DETAILED DESCRIPTION OF THE INVENTION
[0052] Referring in detail to
[0053]
[0054] Referring to
[0055] Prior to cutting, the user determines the amount of offset that he wants to remain after cutting out the window of the workpiece 4. The present invention allows the user to easily register the template cutting guide above the workpiece using the longitudinal and latitudinal grid lines 38 & 39 to measure the desired offset from the start and run of the cutting path 16 to the adjacent peripheral outer edges of the workpiece to be cut. The template cutting guide 20 of this invention is designed to work with any form of grid marking including the use of a substantially transparent body material and marking the longitudinal and latitudinal grid lines 38 & 39 on the bottom of the template cutting guide 20. To use the template cutting guide 20, the user places the planar bottom face surface 27 on to the top surface of the workpiece 4 and orients the template cutting guide by using the longitudinal and latitudinal grid lines 38 & 39 or another means of measuring to measure the required offset. The longitudinal and latitudinal grid lines 38 & 39 are oriented from the location of the angled cut. The user may steady the template cutting guide 20 with one hand, and use his free hand to grasp the cutting tool 8 and place the cutting blade 9 in to the cutting guide slot 30 defined by the cutting slot side walls 32 & 33. Depending on the desired cut the user may use a template cutting guide 20 with a cutting guide slot 30 that runs perpendicular to the face of the workpiece 4 giving a straight cut, or use a template cutting guide 20 with an cutting guide slot 30 that form an acute angle to the face of the workpiece 4 to create a precisely executed beveled cut. This design contemplates the use of a variety of slot angles depending on the slot design chosen for the desired straight or beveled cutting affect.
[0056] Continuing the cutting process the user places one hand on the template cutting guide 20 taking care to not cover the slot applying a downward force with his hand onto the top planar surface of the body 21, more specifically on the holding figure area 31, with sufficient effort to prevent the template cutting guide 20 from moving during the cutting process. Optionally the user may pin the template cutting guide 20 onto the workpiece 4 once he has aligned his cutting path 16, the user using a push pin 29 may insert the push pin needle 75 through the push pin hole 28 in the body 21 and driving the push pin tip 78 into surface of the area of the workpiece 4 that is the internal cutout 10 thus mechanically fastening the template cutting guide 20 to the workpiece 4 without damaging the finished work product.
[0057] With the free hand the user may grasp the cutting tool 8 and inserts the cutting blade 9 of the cutting tool 8 into the cutting guide slot 30 defined by the slot side walls 32 and 33, slot top opening 34 and bottom opening 35 and so that the cutting blade 9 projects below the slot bottom opening 35 sufficiently deep enough to completely penetrate the workpiece 4 illustrated in
[0058] Referring to
[0059] There is a cutting guide slot 50 that runs parallel to the long edge of the elongated sides 52 & 53 of the body 51 and perpendicular to the template cutting guide short ends 54 & 55 to accept the cutting blade 9 of the cutting tool 8. In this embodiment the angle of the cutting guide slot's 50 interior side wall 53 is extended above the guide slot top opening 55 extending the cutting guide 48 to further direct and secure the blade during cutting. The extended cutting guide area 48 allows the user additional stability when the cutting tool 8 and specifically cutting blade 9 are placed into the cutting guide slot 50. The blade guide ridge 49 acts as a shoulder rest for the cutting tool body during cutting as illustrated in
[0060] The raised ridge of the finger guard 51 runs parallel to the cutting guide slot 50 of the template cutting guide 40 of this embodiment. Having a raised finger guard 51 of this design provides a protected and more secure area for the user to place his fingers during cutting. As can be seen in

[0064] The design of this invention may be made out of any number of materials including plastic, metal and glass. A clear glass plastic material can be utilized in the convex lens shape 85 shown in
[0065] This preferred embodiment allows for the use of a commonly available cutting tool 8 and commonly available push pins 79 to work with the template cutting guide of this invention. The invention of this disclosure allows the user the ease of use and adaptability of the straight edge 1 of the prior art while providing the utility of creating a straight through (perpendicular to the surface) or a beveled cut of the workpiece that is the result of the more complicated and expensive cutting assembly 11. The invention of this disclosure can create the professional results illustrated in
