Stab vest

A stab vest, or stab proof vest is a reinforced piece of body armor, worn under or over other items of clothing, which is designed to resist knife attacks to the chest, back and sides. Stab vests are different from bulletproof vests, most of which offer protection against firearms but afford little against stabbing with sharp-tipped objects such as knives; most stab vests afford less protection against bullets, particularly those of high caliber, but are designed to prevent serious injury by prohibiting knife penetration beyond a few millimeters. Stab vests are also needle and slash proof.

Standards

"Ice pick" tests

In the mid-1980s the state of California Department of Corrections issued a requirement for a body armor using a commercial ice pick as the test penetrator. The test method attempted to simulate the capacity of a human attacker to deliver impact energy with their upper body. As was later shown this test over stated the capacity of human attackers. The test used a drop mass or sabot that carried the ice pick. Using gravitational force, the height of the drop mass above the vest was proportional to the impact energy. This test specified 109 joules (81 ft·lbf) of energy and a 7.3 kg (16 lb) drop mass with a drop height of 153 cm (60 in) and an ice pick with a 4 mm (0.16 in) diameter with a sharp tip with a 5.4 m/s (17 ft/s) terminal velocity in the test. The California standard did not include knife or cutting edge weapons in the test protocol. In this early phase only titanium and steel plate offerings were successful in addressing this requirement.

Scream 2

Scream 2 is a 1997 American slasher film directed by Wes Craven and written by Kevin Williamson. It stars Neve Campbell, Courteney Cox, David Arquette, Sarah Michelle Gellar, Jamie Kennedy and Liev Schreiber. Dimension Films released it on December 12, 1997, as the second installment in the Scream film series. Scream 2 takes place two years after Scream and again follows the character of Sidney Prescott (Campbell), now a student at the fictional Windsor College, who becomes the target of a copycat killer using the guise of Ghostface. Sidney is accompanied by film-geek Randy Meeks (Kennedy), retired deputy sheriff Dewey Riley (Arquette) and news reporter Gale Weathers (Cox). Like its predecessor, Scream 2 combines the violence of the slasher genre with elements of comedy and "whodunit" mystery while satirizing the cliché of film sequels. The film was followed by two sequels, Scream 3 (2000) and Scream 4 (2011).

Williamson provided a five-page outline for a sequel to Scream when auctioning his original script, hoping to entice bidders with the potential of buying a franchise. Following a successful test screening of Scream and the film's financial and critical success, Dimension films moved forward with the sequel while Scream was still in theaters, with the principal cast all returning to star, Craven to direct and Beltrami to provide music.

Stab (b-boy move)

The stab is a breakdance technique necessary to perform many downrock and power moves. It is not a distinct move, but is incorporated into many breakdance moves including the turtle, cricket, jackhammer, crab-walk, hand glide, some versions of the windmill, and many other floats and freezes. It allows the breakdancer's entire weight to be supported by bony structures while expending minimal muscular energy to maintain balance.

The stab is accomplished by placing the olecranon process of the elbow firmly against the bones or tensed muscles of the abdomen, side, or back. Perhaps the most basic stab places the elbow against the anterior superior iliac spine. Meanwhile, the hand is placed against the ground. The radius and ulna are held perpendicular to the ground with the weight of the body on either side of the point of contact kept in perfect balance. Assuming this balance is maintained, the rest of the body can then be suspended above the ground in any desired position.
