DETAILED DESCRIPTION

[0027] Referring now to FIG. 4 there is shown a combination electricians tool in accordance with one form of the present invention. The tool includes a pair of arms 40, 42 each including a compressive grip surface disposed on the lower (as viewed) end and a jaw disposed on the upper (as viewed) end, wherein the arms are pivotally connected to one another with a pivot pin or fulcrum 44. A spring 46 biases the jaws to an open position. The compressive grip surface on the arm 40 is characterized by four arcuate recesses dimensioned for the accommodation of the user's fingers. The compressive grip surface on the arm 42 is a single curvilinear recess for accommodating the palm of the user's hand. Thus, the compressive grip surfaces collectively facilitate the user applying greater force to the compressive grip surfaces.

[0028] A pivoting locking tab 48 is configured to selectively lock the assembly in a closed position. The jaws on each arm 40, 42 have a plurality of facing elements sequentially disposed between the upper as viewed extremity of each arm and the fulcrum 44.

[0029] More specifically, at the extremity of the arms 40, 42 most distal from the fulcrum 44 are respective diagonal cutter portions 50, 52 having a construction such as that shown in FIGS. 2 and 3. The arms 40, 42 further include respective axially adjacent sections 54, 56 having a construction corresponding to the linesman jaws 12 illustrated in FIG. 1.

[0030] The arms 40, 42 further include respective sections 58, 60 that collectively provide a wire stripping capability. In addition, respective opposed sections 62, 64 collectively provide a shear cutting capability. Those skilled in the art will recognize that the shear cutting is achieved in the same manner as conventional scissors.

[0031] FIG. 5 is a partially schematic fragmentary side view of the embodiment of the combination electricians tool shown in FIG. 4. This view illustrates, for example, five wires 60 can engage the lineman jaws 12 despite the location of the diagonal cutter 52 outboard of the linesman jaws 12.

[0032] Accordingly, the tool provides the capability of both a diagonal cutter and linesman pliers in a single product. This is achieved despite (1) the conventional rationale of constructing cutting edges to extend very close to the cutting tool pivot inherently motivates the use of multiple tools to accomplish many common tasks and (2) need to isolate the gripping and cutting functions. Accordingly, it is therefore seen that there exists a need in the art to overcome the deficiencies and limitations described herein and above.

[0033] All publications and patent applications mentioned in this specification are indicative of the level of skill of those skilled in the art to which this invention pertains. All publications and patent applications are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference.

[0034] It will be understood that, in general, terms used herein, and especially in the appended claims, are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood that if a specific number of an introduced claim recitation is intended such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of introductory phrases such as “at least one” or “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “an image” should typically be interpreted to mean “at least one image”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, it will be recognized that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two images,” or “a plurality of images,” without other modifiers, typically means at least two images). Furthermore, in those instances where a phrase such as “at least one of A, B, and C,” “at least one of A, B, or C,” or “an [item] selected from the group consisting of A, B, and C,” is used, in general such a construction is intended to be disjunctive (e.g., any of these phrases would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, and may further include more than one of A, B, or C, such as A.sub.1, A.sub.2, and C together, A, B.sub.1, B.sub.2, C.sub.1, and C.sub.2 together, or B.sub.1 and B.sub.2 together). It will be further understood that virtually any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

[0035] Although the description above contains many specifics, these should not be construed as limiting the scope of the invention, but as merely providing illustrations of some of the presently preferred embodiments of this invention. Thus, the scope of this invention should be determined by the appended claims and their legal equivalents. Therefore, it will be appreciated that the scope of the present invention fully encompasses other embodiments which may become obvious to those skilled in the art, and that the scope of the present invention is accordingly to be limited by the appended claims, in which reference to an element in the singular is not intended to mean “one and only one” unless explicitly so stated, but rather “one or more.” All structural, chemical, and functional equivalents to the elements of the above-described preferred embodiment that are known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the present claims. Moreover, it is not necessary for a device or method to address each and every problem sought to be solved by the present invention, for it to be encompassed by the present claims. Furthermore, no element, component, or method step in the present disclosure is intended to be dedicated to the public regardless of whether the element, component, or method step is explicitly recited in the claims. No claim element herein is to be construed under the provisions of 35 U.S.C. 112, sixth paragraph, unless the element is expressly recited using the phrase “means for.”

[0036] This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.
