[citation needed] The screws go under the frame (work-piece) to be held, and the bit clamps down on the lower-edge of the frame. [citation needed] Recent designs are more complicated; a rigid body holds one fixed and one moveable jaw activated by a cam. [citation needed] An example of newer clamps is Jim Chestnut's Clam Clamp.

90º miter joint (pieces ready to be joined) Miter joint of two pipes A miter joint (mitre in British English) is a joint made by cutting each of two parts to be joined, across the main surface, usually at a 45° angle, to form a corner, usually to form a 90° angle, though it can comprise any angle greater than 0 degrees.
The Mogen clamp is then slid over the foreskin. After confirming that the tip of the glans is free of the blades, the clamp is locked, and a scalpel is used to cut the skin from the flat (upper) side of the clamp. In newborns, no sutures are required. Outside of the newborn period, cyanoacrylate tissue adhesive can be used instead of sutures. [8]
The shell of the clam ranges from 15 centimetres (6 in) to over 20 centimetres (8 in) in length, but the extremely long siphons make the clam itself much longer than this: the "shaft" or siphons alone can be 1 metre (3 ft 3 in) in length. The geoduck is the largest burrowing clam in the world. [3]
An aortic cross-clamp is a surgical instrument used in cardiac surgery to clamp the aorta and separate the systemic circulation from the outflow of the heart. [1] An aortic cross-clamping procedure serves, for example, in the repairing of coarctation of the aorta. In newborns, the treatment of choice for this condition is resection and primary ...
The creature in the video is a Pacific razor clam, though it looks enough like a geoduck to befuddle even a knowledgeable biologist: Digging into wet sand is a survival technique for the critter, ...
The name "razor clam" is also used to refer to different species such as the Pacific razor clam (Siliqua patula) or Razor shell (Ensis magnus). Jackknife clams live in sand and mud and are found in intertidal or subtidal zones in bays and estuaries. Its streamlined shell and strong foot allow Jackknife clams to burrow quickly in wet sand.
The name lewis may come from the Latin levo -avi, -atum meaning to levitate or lift, [1] but the Oxford English Dictionary Online [2] states, "the formation and the phonology are not easily explained on this hypothesis", preferring "origin obscure", and speculating that the term may derive from a personal name.
