The most popular shucking method for shucking an oyster is called prying. The oyster is opened from the back or hinge area. Prying is possible because today the knife blades are made of hard metals and cannot be snapped in two by the force of prying.
In prying, the oyster is grasped with either a bar towel or a glove with the flatter side up. The oyster knife is used like a key; locating the seam near the hinge, a shucker inserts a tip and blade of the oyster knife with great force to a position where a twist of the oyster knife opens the oyster shell.
The action of prying requires the exertion of great pressure, is tiring, and straining. Repetitive motion disorders (“RMDs”) are a family of muscular conditions that result from repeated motions performed in the course of normal work or daily activities. RMDs include carpal tunnel syndrome, bursitis, tendonitis, epicondylitis, ganglion cyst, tenosynovitis, and trigger finger. RMDs are caused by too many uninterrupted repetitions of an activity or motion, unnatural or awkward motions such as twisting the arm or wrist, overexertion, incorrect posture, or muscle fatigue. In the case of shucking oysters, the great pressure to insert the oyster knife is also exerted on the socket of the shucker's shoulder tending to draw it out of socket.
Over time, RMDs can cause temporary or permanent damage to the soft tissues in the body—such as the muscles, nerves, tendons, and ligaments—and compression of nerves or tissue. Oyster shuckers often suffer RMDs in and near their right shoulder socket due to the great pressure necessary to insert the knife.
Additionally, the act of inserting the knife can if done improperly propel the knife into the flesh of the left oyster-holding hand. Such knife-induced injuries may result in infection or severing of muscles, tendons, or nerves.
What is needed in the art is a safe apparatus for shucking oysters.
An oyster block includes a base having a generally planar first surface as well as an arcuate bulkhead attached to the base defining, in cooperation with the generally planar first surface, an oyster receptacle. The oyster receptacle securely holds the oyster as the shucker inserts and pries the oyster shell open.
An embodiment of the block includes a first handle on a second surface of the base, the first handle allowing for the ready movement of the block from workplace to workplace, exploiting the portable nature of the block. Because the block is often used in wet environments, an advantageous option includes configuring the handle to include a finger rest with a first series of spaced apart ridges. An additional option is placing a second handle in opposed relationship to the first thereby allowing the block to be securely held in both hands when transported.
In another preferred embodiment, the first surface includes a non-slip surface. The non-slip surface might be inset into the first surface or, in an additional embodiment the non-slip surface is a non-slip mat.
Advantageously, the base may optionally be configured to include a receptacle configured to hold an oyster knife. The base may also include a holding means for securing an oyster knife within the receptacle. In an embodiment, the holding means is a magnet.
An additional embodiment includes a base that is formed of a monolithic solid prism allowing single step manufacturing of the block.
Preferred and alternative embodiments of the present invention are described in detail below with reference to the following drawings.
Depressions 18a and 18b are configured to allow access to the knot of the oyster when the oyster is received in the oyster receptacle 12. A rest 15 is provided on an upper surface of the shucking block 11 to allow one hand to hold the block against a work surface and secure the oyster in the oyster receptacle 12.
A second surface 14, which is generally perpendicular to the first surface 12, optionally includes a defined cutout 21 that serves as a first handle to assist in moving the block from an engaging position relative to the tabletop or counter. The block is a portable device, so having a handle makes it easier to carry from place to place. A first series of spaced apart ridges 21a extend to and in concert with the cutout 21 serve to form a finger rest. The series of spaced apart ridges 21 forms a self-cleaning, non-fouling surface that allows a secure grip when the fingers may be covered with the viscera of shucked oysters.
Optionally, a receptacle 32 is defined for storing an oyster knife 30 on the underside of the block 11 by suitable means. Where present, the receptacle reduces the likelihood of losing the oyster knife 30. In one embodiment, a magnet 27 secures the knife 30. This is a simple, but effective means to secure the oyster knife 30 by attracting the metal blade of the oyster knife 30. Other suitable catchment devices may optionally be used to retain the oyster knife 30 within the receptacle 34.
While the preferred embodiment of the invention has been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. For example, the oyster knife may be secured to the underside of the block by many methods other than a magnet, including but not limited to a latch, a cover, a clip, or a receptacle configured such that it has somewhat flexible sides that grip the oyster knife when inserted. Also, for example, rather than using a non-slip mat, all or a portion of the first surface may be formed of a non-slip material or rather than using non-slip feet, all or a portion of the fourth surface may be formed of a non-slip material. Additionally, the surfaces and regions of the base may be formed of separate parts that when attached or bonded together form the block or the base may be made of a monolithic material which is configured such that all of the surfaces and regions are formed from a single part.
