## Abstract

A utensil to open a shell of a shellfish, including a first end including a shell breaking tool, a second end including a fork, and a handle to connect the first end to the second end, such that at least a portion of a bottom surface of the handle includes a sharpened edge.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present general inventive concept relates to a shell-opening utensil for facilitating the opening and removal of meat from crab bodies, crab legs, and other types of shellfish, and particularly to a shell-opening utensil to sever a shell of a shellfish, extract meat out of an opened shellfish if the meat has not been fully exposed by the severing operation, and to break open areas of the shell which are normally difficult to crack and open, in order to expose the meat for extraction.
2. Description of the Related Art
Crustaceans (e.g., shellfish) such as crabs and lobsters are often prepared for eating by cooking and serving the shellfish while still in a shell. The shell must be removed or broken away from the meat before the meat can be consumed. Boiling or broiling of a shellfish such as a crab, for example, typically does not change characteristics of the shell to an extent that it can be easily broken to access the meat of the crab.
Conventional shell-opening utensils include bifurcated, pivoted handle, nutcracker-type utensils, which have been used to crack the shells of crab legs or other types of shellfish in order to facilitate manual removal of the shellfish meat from the protective shell. However, the nutcracker-type utensils are only useful for opening crab and lobster legs, and do not allow a user to open a body of a crab or a tail of a lobster. Also, the nutcracker-type utensils are relatively expensive, and therefore result in a relatively large cost for restaurants when these nutcracker-type utensils are stolen by customers. Furthermore, the nutcracker-type utensils do not allow the user to easily extract the meat from the shell after it is open. Moreover, the nutcracker-type utensils are not particularly useful in when shells that are somewhat soft, and mere cracking of the shell often does not allow the user to then easily remove meat from the cracked shell, such as with shrimp and prawn. Finally, the nutcracker-type utensils do not provide a mechanism for removing hard-to-access meat, and the user typically needs to use a fork for meat extraction.
Other conventional shell-opening utensils include a combination utensil, such as the invention described in U.S. Pat. No. 7,134,206, include a combination of a crustacean shell breaking tool at one end, and a fork at another end. However, the combination utensil is also limited only to allowing a user to open claws and tails of crustaceans, and do not allow the user to sever a body of a crab. Moreover, the combination utensil has design flaws, as it is difficult to maintain a good grip of the combination utensil as it is used to sever a crab claw, for example.
Further conventional shell-opening utensils include oyster, clam, and mussel openers, also known as “shuckers.” However, shuckers are typically only used to open raw oysters and clams, and are not readily offered to customers to use in a restaurant when they order jambalaya, Cajun seafood boils, or other dishes that serve multiple types of seafood including cooked clams, mussels, and oysters. Also, shuckers are typically made of metal, and are therefore expensive to produce and purchase.
Therefore, there is a need for a single multifunctional shell-opening utensil that allows a user to open multiple types of shellfish in multiple ways, and then extract meat from the opened shellfish.
SUMMARY
The present general inventive concept provides multifunctional shell-opening utensil to allow a user to open various types of shellfish to easily extract meat therefrom.
Additional features and utilities of the present general inventive concept will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the general inventive concept.

FIG. 1A illustrates a side view of a multifunctional shell-opening utensil 1, according to an exemplary embodiment of the present general inventive concept.
Referring to FIG. 1A, the multifunctional shell-opening utensil 1 may include a first end 100, a second end 200 that is opposite the first end 100, and a handle 300 separating the first end 100 and the second end 200.
The first end 100 may be formed in a shape of a shell-breaking tool 101 including a first member 110 extending longitudinally away from the handle 300, and a second member 120 disposed adjacent to the first member 110 and extending longitudinally away from the handle 300, such that a gap 130 is defined between at least a portion of the first member 110 and the second member 120.
Referring to FIG. 1A, the multifunctional shell-opening utensil 1 may be formed of a single piece of plastic, metal, ceramic, or any other type of durable composition, but is not limited thereto. Alternatively, the multifunctional shell-opening utensil 1 may include various pieces attached and fixed together using glue, welding, etc.
The first end 100 may include a shell breaking tool 101, to allow a user to break open a claw shell of a crab or a lobster, for example.
The shell breaking tool 101 may include a first member 110, a second member 120, and a slot 130 disposed between the first member 110 and the second member 120. The slot 130 may be a gap between the first member 110 and the second member 120, and may have a predetermined and/or varying size based on a user's preference.
The first member 110 may extend laterally (i.e., longitudinally) from the first end 100.
The first member 110 may include an outer surface 111, an inner surface 112, an extended portion 113, and a wedge portion 114.
The outer surface 111 may be rectangular, rounded, flat, trapezoidal, or have any other shape to maximize its strength.
The inner surface 112 is disposed opposite the outer surface, and may have a shape similar to or different from the outer surface 111, in order to maximize its strength.
The extended portion 113 may be connected to the first member 110 to extend laterally (i.e., longitudinally) from the first end 100. The extended portion 113 may be extended from the first end 100 at various distances, and therefore is not limited to a length as illustrated in FIG. 1A.
The extended portion 113 may include a wedge portion 114 at an end thereof.
The wedge portion 114 may include an inclined surface 115 and a chisel tip 116. Although FIG. 1A illustrates the inclined surface 115 beginning from the inner surface 112 and extending upward toward the outer surface 111 to the chisel tip 116, alternatively, the inclined surface may begin from the outer surface 111 to extend downward toward the inner surface 112 to the chisel tip 116.
The extended portion 113, the wedge portion 114, the inclined surface 115, and the chisel tip 116 may all be included in the present general inventive concept as a shucking tool 117, in order to allow the user to shuck an oyster shell, clam shell, or mussel shell. More specifically, the chisel tip 116 may be a sharpened edge to allow the user to wedge the shucking tool 117 into a mussel shell, for example, while the inclined surface 115 pries the mussel shell open until at least a portion of the extended portion 113 is inside the semi-opened mussel shell. Then, the user may rotate (i.e., twist) the handle 300 in order to cause the extended portion 113 to pry open the mussel shell substantially to allow meat inside the mussel shell to be accessed.
The second member 120 may include an inner edge 121, a splitting edge 122, a serrated portion 123, a point tip 124, and an outer edge 125.
The inner edge 121 (a.k.a., inner surface) may be tapered in order to form a sharp edge, or may alternatively include the serrated portion 123 to facilitate in cutting open a claw shell, for example. The splitting edge 122 is located near the first member 110, and may also be sharpened (i.e., tapered) in order to facilitate in splitting open the claw shell. The point tip 125 may also be used to puncture the claw shell in order to aid in the weakening and severing of the claw shell. The second member 120 may also be known as a claw shell breaking tool 126.
The outer edge 125 may be rectangular, rounded, flat, trapezoidal, or have any other shape to maximize its strength, so that the claw shell may be successfully severed while maintaining the integrity of the second member 120.
When the user desires to split open the claw shell, for example, the second member 120 may first be inserted into an end of the claw shell as much as the slot 130 permits, until the splitting edge 122 contacts the claw shell. Then, the user may apply an upward force to simultaneously puncture the claw shell with the point tip 124, while also applying a forward motion in a lateral direction of the claw shell to utilize the splitting edge 122 to sever the claw shell along its lateral axis. As the claw shell continues to be split, the user continues to apply the upward and forward motions to fully split the claw shell, until meat inside the claw shell is easily accessible.
Accordingly, the first end 100 of the present general inventive concept may include both the shucking tool 117 and the claw shell breaking tool 126, but is not limited thereto.
Referring to FIG. 1A, the second end 200 may include a fork 210.
The fork 210 may include a body 220, a first tine 230, a second tine 240, and a center tine 250. The center tine 250 may be disposed between the first tine 230 and the second tine 240, such that the first tine 230, the second tine 240, and the center tine 250 are all disposed on a same plane.
The first tine 230 may include a body portion 231 and a tip 232.
The body portion 231 may have a plurality of shapes, including straight, concave, and convex, depending on a user's preference.
The tip 232 may be pointed (i.e., relatively sharp) in order to allow the user to puncture meat out of a shell of a shellfish. The tip 232 may have a variety of different shapes, including straight, hooked inward toward the center tine 250, hooked outward away from the center tine 250, hooked upward, or hooked downward.
The second tine 240 may include a body portion 241 and a tip 242.
The body portion 241 may have a plurality of shapes, including straight, concave, and convex, depending on a user's preference.
The tip 242 may be pointed (i.e., relatively sharp) in order to allow the user to puncture meat out of a shell of a shellfish. The tip 242 may have a variety of different shapes, including straight, hooked inward toward the center tine 250, hooked outward away from the center tine 250, hooked upward, or hooked downward.
Although FIG. 1A illustrates the center tine 250 as part of the fork 210, the center tine 250 may be optional, and a manufacturer may choose to omit the center tine 250 to allow the fork 210 to be more compact. Otherwise, the center tine 250 may include a body portion 251 and a tip 252.
As illustrated in FIG. 1A, the fork 210 may be disposed at the second end 200, such that a plane upon which the first tine 230, the second tine 240, and the center tine 250 are disposed is parallel to (i.e., in-line with) a first side surface 330 and a second side surface 340 of the handle 300. Alternatively, the fork 210 may be disposed at the second end 200, such that a plane upon which the first tine 230, the second tine 240, and the center tine 250 are disposed is perpendicular to the first side surface 330 and the second side surface 340 of the handle 300.
The fork 210 may be utilized by the user to extract any meat from any shell that has been opened by other portions of the multifunctional shell-opening utensil 1.
Referring to FIG. 1A, the handle 300 may include a top edge 310, a bottom edge 320, the first side surface 330, the second side surface 340, a first projecting portion 350, and a second projecting portion 360. The first projecting portion 350 and the second projecting portion 360 may also be called “finger grips,” “finger rests,” “shark fins,” and “protruding portions.”
The top edge 310 may be rectangular, rounded, flat, trapezoidal, or have any other shape to maximize its strength.
The bottom edge 320 is disposed opposite with respect to the top edge 310, and may be tapered (i.e., sharpened) with a tapered portion 321, in order to form a “knife-like” edge. Alternatively, the bottom edge 320 may have a variety of shapes that imitate an edge of a knife, based on the user's preference.
The first side surface 330 is disposed opposite with respect to the second side surface 340, and both the first side surface 330 and the second side surface are disposed between the top edge 310 and the bottom edge 320.
The bottom edge 320 may be used as a body bisecting tool to bisect a crab body, for example.
The first projecting portion 350 may be disposed on at least a portion of the bottom edge 320 of the handle 300, preferably at a location near the first end 100, and may include a gripping portion 351 and a back portion 353.
The gripping portion 351 (a.k.a., concave portion 351) may be provided as a concave grip for a forefinger of a user to be used when the user is using the claw shell breaking tool 126 to open the claw shell. The gripping portion 351 may face the first end 100. The gripping portion 351 may include a roughened portion 352 in order to provide a non-slick surface for the user's forefinger. Specifically, the roughened portion 352 may include a ribs, protruding dots, or any other type of surface that allows the forefinger of the user to have superior traction on the gripping portion 351.
The back portion 353 may be convex, as illustrated in FIG. 1A. Alternatively, the back portion 353 may be concave, similar to the gripping portion 351, in order to provide alternative gripping options for the user.
The second projecting portion 360 may be disposed on at least a portion of the top surface 310 of the handle 300, preferably at a location near the first end 100, but further from the second end 200 than the first projecting portion 350. As such, a relative distance between the first projecting portion 350 and the second projecting portion 360, and with respect to the second end 200, allows the user to have a superior grip on the multifunctional shell-opening utensil 1. However, the roughened portion 352 is optional, and the gripping portion 351 may be smooth.
The second projecting portion 360 may include a gripping portion 361 and a back portion 363.
The gripping portion 361 (a.k.a., concave portion 361) may be provided as a concave grip for a thumb of a user to be used when the user is using the claw shell breaking tool 126 to open the claw shell. The gripping portion 361 may face the second end 200. The gripping portion 361 may include a roughened portion 362 in order to provide a non-slick surface for the user's forefinger. Specifically, the roughened portion 362 may include a ribs, protruding dots, or any other type of surface that allows the thumb of the user to have superior traction on the gripping portion 361. However, the roughened portion 362 is optional, and the gripping portion 361 may be smooth.
The back portion 363 may be convex, as illustrated in FIG. 1A. Alternatively, the back portion 363 may be concave, similar to the gripping portion 361, in order to provide alternative gripping options for the user.
The first projecting portion 350 and the second projecting portion 360 may be optional, and may be provided as part of the handle 300 in order to facilitate the user's grip when utilizing the multifunctional shell opening utensil 1.
