Pocket Knife
A pocketknife is a knife with one or more blades that fold into the handle. They are also known as jackknives (jack-knife), folding knives, or may be referred to as a penknife, though a penknife may also be a specific kind of pocketknife. A typical blade length is . Pocketknives are versatile tools, and may be used for anything from whittling and woodcarving, to butchering small game, gutting and filleting small fish, aiding in the preparation of tinder and kindling for fires, boring holes in soft material, to opening an envelope, cutting twine, slicing a piece of fruit or as a means of self-defense. Specialised designs are also used for mushroom hunting and gardening. Pocketknives designed for gardening include pruning knives, which are folding knives with long curved blades used for pruning, trimming cuttings, taking buds and preparing material for grafting. History The earliest known pocketknives date to at least the early Iron Age. A pocketknife with a bone handle wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jackknife Bar
Jackknife Bar, or simply Jackknife, was a bar in Portland, Oregon. The 4,000-square-foot cocktail bar was housed in the Sentinel Hotel, before closing in May 2020, during the COVID-19 pandemic. Description The interior featured a 50-seat, 65-foot-long curved marble and wood-lined bar, as well as a domed stained glass ceiling. History Jake Carey and John Janulis opened the bar in April 2014, with Justin Diaz overseeing the bar operation and Erik Paulsen as chef. Russell Van der Genugten became executive chef in March 2015. In 2019, a man was removed from the bar for wearing a shirt with the text "Anti-Fascist"; Jackknife's parent company Lightning Bar Collective ( Bye and Bye, Sweet Hereafter, Victoria Bar) said the policy against clothing promoting hate groups was "misinterpreted" by a contracted security guard. The bar closed in May 2020, during the COVID-19 pandemic. Reception ''Eater'' included Jackknife in a list of the "most beautiful restaurants" in the U.S. Samantha Ba ...

Jackknifing
Jackknifing is the folding of an articulated vehicle so that it resembles the acute angle of a folding pocket knife. If a vehicle towing a trailer skids, the trailer can push the towing vehicle from behind until it spins the vehicle around and faces backwards. This may be caused by equipment failure, improper braking, or adverse road conditions such as an icy road surface. In extreme circumstances, a driver may attempt to jackknife the vehicle deliberately to halt it following brake failure. Trailer swing When a trailer skids to one side, this is known as a trailer swing or trailer slew. This can occur on a slippery road surface, often where there is a cant. This is not the same as jackknifing and is not as serious, as the trailer will move back into line as the vehicle continues forwards. The driver must be aware, however, that the trailer could slide up against parked cars or a guard rail, or that the wheels could slide into a ditch. This situation can occur especially when ...

Jacknife
''Jacknife'' is a 1989 American film directed by David Jones and starring Robert De Niro, Ed Harris and Kathy Baker. The film focuses on a small, serious story, with emphasis on characterization and the complex tension between people in a close relationship. Stephen Metcalfe, upon whose play ''Strange Snow'' (1982) the film was based, wrote the screenplay. Harris was nominated for a Golden Globe for his performance. Plot Joseph Megessey (known to most as Megs) is a Vietnam war veteran suffering post-Vietnam stress syndrome who is having trouble fitting in with society. He takes on the responsibility of drawing Dave, a fellow veteran who has become an alcoholic, out of his shell by coaxing him to enjoy life again, as well as urging him to face up to some of his darker memories. Megs finds himself attracted to Dave's meek sister Martha, who lives with Dave and looks after him. This attraction leads to a love affair, much to Dave's disapproval. Dave eventually vents his anger a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Superjail!
''Superjail!'' is an American adult animated television series produced by Williams Street. It follows the events that take place in an unusual prison. The pilot episode aired on television on May 13, 2007, and its first season began on September 28, 2008 on Cartoon Network's late night programming block, Adult Swim.

540 Kick
In martial arts and tricking, the 540 kick (Chinese:旋風腳 (''Xuanfengjiao'')) (also known as inside turning kick, jump inside kick, and "hyper" tornado kick) is a jump kick move. It involves a rotation of approximately 540 degrees (although when performed correctly the performer has only done a spin of 360 degrees – not including whatever takeoff used). It is practiced in various disciplines including Taekwondo, Tang Soo Do, Wushu, Shaolin Quan, Capoeira and some Karate styles but traditionally most associated with the Korean martial arts. However, the most prominent defining feature is that the same leg is used for taking off, kicking, and landing. The other leg is used to propel the performer into the air, and is then retracted before landing. Many martial arts tricksters choose this move as their first move to attempt. This move has a history in ballet as well, where it is performed as an advanced variation of a 'barrel roll'. Principal male ballet dancers include t ...

Pin (professional Wrestling)
In wrestling, a pin is achieved by holding an opponent's shoulders to the mat for a three count. Pinfall is the term used in professional wrestling which is a way to win the match for that person or team. Background A pinfall is a victory condition in various forms of professional wrestling that is met by holding (pinning) an opponent's shoulders on the wrestling mat, usually until the referee counts to three. In professional wrestling, a pinfall is a common method of winning a match. The origin of the pinfall is the pin from amateur wrestling, whereby pinning an opponent to the mat will result in a victory despite any points scored. However, while an amateur wrestling pin need be only one or two seconds, the count in professional wrestling is based on the referee's arm gestures, regardless of how much actual time elapses, and is to three slaps of the mat. The count is broken (a near-fall) if the opponent manages to raise one or both of their shoulders off the mat, commonly by ...

Jackknife (statistics)
In statistics, the jackknife (jackknife cross-validation) is a cross-validation technique and, therefore, a form of resampling. It is especially useful for bias and variance estimation. The jackknife pre-dates other common resampling methods such as the bootstrap. Given a sample of size n, a jackknife estimator can be built by aggregating the parameter estimates from each subsample of size (n-1) obtained by omitting one observation. The jackknife technique was developed by Maurice Quenouille (1924–1973) from 1949 and refined in 1956. John Tukey expanded on the technique in 1958 and proposed the name "jackknife" because, like a physical jack-knife (a compact folding knife), it is a rough-and-ready tool that can improvise a solution for a variety of problems even though specific problems may be more efficiently solved with a purpose-designed tool. The jackknife is a linear approximation of the bootstrap. A simple example: Mean estimation The jackknife estimator of a parame ...
