Question: Custom knifemaker Gil Hibben designed the knifes used by Ed Parker in this martial art characterized by the use of quick and powerful strikes delivered from the body's natural weapons, powered by rapid stance transitions?
Context: Ernest R. Emerson (born March 7, 1955) is an American custom knifemaker, martial artist, and edged-weapons expert.  Originally an engineer and machinist in the aerospace industry, Emerson became a knifemaker by producing knives for a martial arts class and making art knives early in his knifemaking career.  In the 1980s he became better known for his combat knives and popularizing a style of knife known as the Tactical-folder. The Linerlock is a locking mechanism for folding pocket knives.  A Linerlock is a folding knife with a side-spring lock that can be opened and closed with one hand without repositioning the knife in the hand.  The lock is self-adjusting for wear.  The modern Linerlock traces its lineage to the late 19th century, but in the 1980s the design was improved by American custom knifemaker Michael Walker. In Japanese martial arts, the term atemi (当身 ) designates blows or strikes to the body, as opposed to twisting of joints, strangleholds, holding techniques and throws.  Atemi can be delivered by any part of the body to any part of the opponent's body.  They can be percussive or use "soft" power.  Karate is a typical martial art focusing on percussive atemi.  The location of nerve and pressure points, such as might be used for certain acupressure methods, also often informs the choice of targets for atemi (see kyusho). American Kenpo ( , pronounced KeMpo) is a martial art characterized by the use of quick and powerful strikes delivered from all of the body's natural weapons, powered by rapid stance transitions.  The beginner is introduced to numerous basics that comprise the system taught through the vehicle of scripted ideal scenarios that give instructors a platform from which to introduce the concepts and principles that Ed Parker emphasized in his teachings of American Kenpo. Angampora (Sinhalese: අංගම්පොර , is a form of martial art from Sri Lanka that combines combat techniques, self-defense, sport, exercise, and meditation.  A key component of angampora is the namesake "angam", which incorporates hand-to-hand fighting, and "illangam", involving the use of indigenous weapons such as the ethunu kaduwa, staves, knives and swords.  Another component known as "maya angam", which uses spells and incantations for combat, is also said to have existed.  Angampora's distinct feature lies in the use of pressure point attacks to inflict pain or permanently paralyze the opponent.  Fighters usually make use of both striking and grappling techniques, and fight until the opponent is caught in a submission lock that they cannot escape.  Usage of weapons is discretionary.  Perimeters of fighting are defined in advance, and in some of the cases is a pit.  With the advent of colonialism over the entirety of the island in 1815, Angampora fell into disuse and was very nearly lost as a part of the country's heritage.  The British administration prohibited its practice due to the dangers posed by a civilian populace versed in a martial art, burning down any "angan madu" (practice huts devoted to the martial art) found: flouting of the law was punished by a gunshot to the knee, effectively crippling practitioners; Angampora nevertheless survived within a few families, allowing it to emerge into mainstream Sri Lankan culture post-independence. Kara-Ho Kempo (the unity of spirit, mind, soul and body, fist law) is a martial art created in the 1930s by the late William Kwai Sun Chow of Hawaii (July 3, 1914 - September 21, 1987).  The system can best be described as a series of rapid strikes (punches and kicks) to the vital areas of an opponent.  The system calls for an equal use of both the hands and feet and, also, teaches self-defense techniques against weapons and multiple attackers. Taekkyeon is a traditional Korean martial art first explicitly recorded during the Joseon Dynasty.  Taekkyeon is characterized by fluid, dynamic footwork called ""pum balgi"" or Stepping-on-Triangles.  Taekkyeon has many leg and whole-body techniques with fully integrated armwork.  Although taekkyeon primarily utilizes kicking, punching, and arm strikes thrown from a mobile stance and does not provide a framework for groundfighting, it does incorporate a variety of different throws, takedowns, and grappling techniques to complement its striking focus.  The martial art is frequently romanized informally as Taekgyeon, Taekkyon, or Taekyun. Taijutsu (体術 , literally "body technique" or "body skill") is a Japanese blanket term for any combat skill, technique or system of martial art using body movements that are described as an empty-hand combat skill or system.  The term is commonly used when referring to a traditional Japanese martial art but has also been used in the naming of modern martial arts such as Bujinkan Budo Taijutsu.  Taijutsu is similar to Karate but is more focused on the body techniques.  More specific names than taijutsu are typically used when describing a martial art, such as jujutsu (focusing on throwing, grappling, and submission), judo (focusing on throwing and grappling), aikido (focusing on throwing and joint locks) as well as karate and kenpō (focusing on striking). Buster Warenski (June 5, 1942 – July 31, 2005) was an American custom knifemaker from Kimberly, Nevada who made "Art Knives" utilizing gold and other precious metals.  Warenski is best known for making a reproduction of King Tut's dagger with a forged gold blade; over 32 ounces of gold were used in the construction of the dagger, making it one of the most valuable knives made in recent years. Gil Hibben (born September 4, 1935) is an American custom knifemaker from Wyoming who is based in La Grange, Kentucky.  Hibben designed the first line of Browning hunting knives in 1968, the American Kenpo Knife for Ed Parker, and the Rambo Knife for the films "Rambo III" and "Rambo".  Hibben's "Fantasy Knives" have been used in over 37 films and television shows, particularly science fiction, earning him the title "Klingon Armorer" from the "Star Trek" franchise.  Hibben currently serves as a President of the Knifemakers' Guild, a post he has held for five years.
