DETAILED DESCRIPTION OF THE INVENTION

(10) The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

(11) Broadly, an embodiment of the present invention provides a hand-operated, two-blade shearing device providing a pincer operatively associated with each blade, the two pincers being dimensioned and adapted to work in concert along with the shearing to also securely pinch and hold the object sheared by the two blades.

(12) It should be understood by those skilled in the art that the use of directional terms such as downward and the like are used in relation to the illustrative embodiments as they are depicted in the figures, the downward direction (bottom) being toward the bottom of the corresponding figures; specifically, FIGS. 3 and 4, where downward is toward the bottom of FIGS. 3 and 4. The upward directions being directed toward the top of FIGS. 3 and 4.

(13) Referring to FIGS. 1 through 9, the present invention may include a hand-operated shearing device 100 having a first blade 10/60 and a second blade 20/60 pivotably connected about a pivot 30/70 so that the respective sharpened edges 11 and 21 slide against each other when the first and second handles 12/52 and 22/62, respectively, opposite to the pivot 30/70 are closed. The pivot 30/70 may be a pin operatively housed in a pin slot 28. The first and second blade 10/60 and a second blade 20/60 and handles 12/52 and 22/62 may be various lengths and shapes as long as they function in accordance with the disclosure herein.

(14) A first pincer post 14/54 is disposed orthogonally from the first blade 10/50 a predetermined distance inward of the first sharpened edge 11, while a complementary second pincer post 24/64 is disposed orthogonally from the second blade 20/60 a predetermined distance inward of the second sharpened edge 21. In certain embodiments, the first pincer post 14/54 may extend vertically from the first blade 10, while the second pincer post 24/64 may be connected to an arm 25 spaced apart from the second blade 20/60 at the location of the second pincer post 24/64. The spaced apart distance may be equal or greater than a distance associated with a thickness of the first sharpened edge 11, thereby allowing the first sharpened edge 11 to slide between the arm 25 and the second blade 20/60. The arm 25 may have a distal end that tapers downward to connect to the second blade 20/60 adjacent to or just inward of the trailing edge 27 of the second blade 20/60 (opposite the leading, sharpened edge 21).

(15) In certain embodiments, the pincer posts 14, 24, 54, and 56 may have a length greater than a width. Specifically, the direction the pincer posts 14, 24, 54, and 56 extend from the upward-facing surfaces of the blades 20/60 is the length along a longitudinal axis. The length may be a length distance that is from more than one to five or more times a width distance of the width. The width distance (i.e., in certain embodiments, the distance orthogonal to the longitudinal axis) may be one-one sixteenth of an inch to one inch.

(16) In certain embodiments, the pincer posts 14, 24, 54, and 56 may extend only orthogonal to the (upward-facing surfaces of the) blades 20/60. Furthermore, it is understood that even though portions of the pincer posts 14, 24, 54, and 56 (like the rear surface) may or may not be non-linear shapes, the pincer posts 14, 24, 54, and 56 may extend along their longitudinal axis in such a ways that they generally maintain a consistent or uniform cross section, wherein the longitudinal axis may or may not be only orthogonal to the surface of the blades 20/60. The direction of the length distance may also be considered vertical or upward.

(17) The first and second pincer posts 14/54 and 24/64 provide operative surfaces 16 and 26, respectively, each having a plurality of serrations or protrusions for gripping. The operative surfaces 16 and 26 may be otherwise planar and facing each other in a closed position. The operative surfaces 16 and 26 may be inward of their respective sharpened edge 11, 21 a predetermined distance of one-sixteenth to one-eighth of an inch so that just prior to a stem 44 being cut completely through by the first and second sharpened edges, 11 and 21, both operating surfaces 16 and 16 are engaging opposing circumference points of said stem 44, as illustrated in FIG. 7. The sharpened edge 11 and 21, may provide a notch adjacent its respective pincer post for identifying the optimal point along the sharpened edges 11 and 21 to engage the stem 44 in a secure engagement.

(18) A method of using the present invention may include the following. The hand-operated shearing device 100 disclosed above may be provided. A user interested in cutting a dead flower 42 of a plant 40 could cut the stem 44 to facilitate the bloom of the next rose by using the hand-operated shearing device 100. The user would align the stem 44 between the first and second pincer post 14/54 and 24/64 and manipulate the handles 12/52 and 22/62 to shear the stem 44 while also securing the severed stem 44 between the two operating surfaces 16, 26 of the first and second pincer post 14/54 and 24/64. From there, the user can lift the shearing device 100 and thus the severed stem 44 and dead flower 42 in the secured engagement to properly dispose thereof.

(19) Additionally, the present invention can be used to cut grapes from a vine without dropping the severed clusters. Alternatively, the present invention could be used to clamp a small artery while cutting contiguous tissue or used during other cut-and-grip surgical procedures.

(20) It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
