Rune Torbjörn Evrell (March 29, 1920 – April 22, 2008) was a Swedish inventor and businessman who made major innovations in folding knife construction, knife designs and knife production methods at EKA-knivar AB Eskilstuna, Sweden.
Born 1920 in Stockholm, Lidingö. Between the age of 11 and 12 he lived in Muncie Indiana, USA. His father, Kaleb Evrell, developed a patent for an automatic transmission for passenger cars for Warner Gears. After the US experience the family moved to Eskilstuna.
Torbjörn Evrell received his degree mechanical engineering in 1945 from the Royal Institute of Technology. His first job was at Centrala Torpedverkstaden, CTV (Torpedo factory of the Swedish Defence Industries) in Motala.
In 1946 Torbjörn Evrell took management of Eskilstuna Knivfabriks AB (EKA) knife making company when the owner John Elmquist (Evrells father in law) unexpectedly died. Evrell, specialist in submersible motors and pumps, now became President of EKA at the age of 26. He took over a company, which in many respects was using production methods of the late 1800s, with a rather outdated machinery with many processes with belt drive from hydropower. Evrell started modernisation . Production technology was improved and the old knife range cut down and new modern knives had to be developed. Evrell first task was to clean up the knife range. He took out a full sales statistics and noted that many models were marginal to sales or outdated. He considered that he could immediately reduce the number of models from 91 to 37. Moreover, he introduced standard components which could be used in several knives.
Evrell also introduced a new systematic production planning, improved methods and machinery were upgraded. Everything to make better knives cheaper. Evrell started using subcontractors and concentrated construction and production to knives.
He was throughout his career continuously involved in all areas of the company including knife innovation, production and marketing. There are a number of influential knife patents in his name. Out of the one time many dozens of knife making companies of Eskilstuna, his was the only one to survive by constant innovation and adaptions to new conditions.
Evrell was the president of EKA until 1985, when he was succeeded by his daughter Karin Ingelson. Torbjörn Evrell continued as an advisor to EKA, especially in product development, for ten more years.
Prior to 1970, all knives were riveted. Riveting was done by hand, and all work with assembly and adjustment, requires craftsmanship which is very labor-intensive. It took at least three to four years for a workman to reach the skill and speed required in production. Evrell realized the problems and wanted to find a faster and less labor-intensive method, while at the same time make the world's best folding knife with one blade. An effort started in November 1967 to come up with a new construction to hold a knife together. The final version of the knife was improved by two external consultants to the company: Olle Nordlund and the industrial designer Sigvard Bernadotte U.S. Patent D227071 . The results were presented in March 1970 when Evrell could launch the first bolted folding knife in the Swede series. The first two models were named Swede 38 (design Sigvard Bernadotte) and Swede 45. The special features of the Swede knives is that the scales are screwed in place. The knife scales can easily be removed, with a screwdriver or coin, for cleaning and lubrication of the blade and inside. The screws are also used to adjust the blade folding mechanism. This new way to manufacture folding knives was completely revolutionary and came to mean a big international breakthrough for EKA. The Swede series started with the EKA Swede 38 knife with plastic scales (offered in several colors) and brass screws with a blade in either carbon steel or stainless steel. The Swede 45 had wooden scales. These first models have been followed by several models with incremental developments.
Another of Evrells inventions is a small folding knife where the whole knife including the folding mechanism is welded together.
With increasing demand EKA-knivar continually made improvements to production methods. The production capacity was increased significantly. In 1971 the company with factory and office in central Eskilstuna was moved to newly built premises at Sättargatan 4 in Vilsta industrial area.
Torbjörn Evrell was very aware of the value of marketing a knife. In 1967 he established a dedicated marketing department within his company, which was of great importance to the company's continued expansion. He also took advantage of the marketing value in a knife. All knife models have been available for branding and adaptation as promotional gifts to mark a sign of quality.
The Swiss Army knife is a multi-tool pocketknife manufactured by Victorinox. The term "Swiss Army knife" was coined by American soldiers after World War II due to the difficulty they had in pronouncing "Offiziersmesser", the German name.
A switchblade is a type of knife with a folding or sliding blade contained in the handle which is extended automatically by a spring when a button, lever or switch on the handle or bolster is activated. Most switchblade designs incorporate a locking blade, in which the blade is locked against closure when the spring extends the blade to the fully opened position. The blade is unlocked by manually operating a mechanism that unlocks the blade and allows it to be folded and locked in the closed position.
Victorinox is a knife manufacturer and luxury watchmaker based in the town of Ibach, in the Canton of Schwyz, Switzerland. It is well known for its Swiss Army knives. The Swiss Army knives made by Victorinox are made of a proprietary blend steel from Germany and France.

A pocketknife is a foldable knife with one or more blades that fit inside the handle that can still fit in a pocket. It is also known as a jackknife (jack-knife) or a penknife, though a penknife may also be a specific kind of pocketknife. A typical blade length is 5 to 15 centimetres. Pocketknives are versatile tools, and may be used for anything from opening an envelope, to cutting twine, slicing a piece of fruit or even as a means of self-defense.
A gravity knife is a knife with a blade contained in its handle, and that opens its blade by the force of gravity. As the gravity knife requires gravity or spinning motion to propel the blade out of the handle, it differs fundamentally from the switchblade, which opens its spring-propelled blade automatically upon the push of a button, switch, or fulcrum lever. The main purpose of this opening method is that it allows opening and closing to be done one handed, in situations where the other hand is occupied. A major historical use has been in issue to parachutists to cut off their parachutes when tangled in a tree or in similar situations.
Buck Knives is an American knife manufacturer founded in San Diego, California and now located in Post Falls, Idaho. The company has a long history through five generations of the Buck family from 1902 to the present day. Buck Knives primarily manufactures sport and field knives and is credited with inventing the "folding hunting knife" and popularizing it to such a degree that the term "buck knife" has become synonymous with folding lockback knives, including those made by other manufacturers.
A pantographic knife or (incorrectly) paratrooper knife is a folding knife whose blade is opened by a unique scissors method. The blade has a slightly longer tang than a folding knife heel. The handle is symmetrically segmented and articulated to fold away on both sides to grip the longer tang. The manner is similar to a balisong knife —with which it is often confused. Unlike the balisong knife handles that swing freely and independently, the pantographic knife uses a pantograph linkage to keep the handles aligned during opening and closing. The pantographic knife is very strong when compared to most other folding knife designs, being joined at several points and along several planes—this increases the force required to break the blade away from the handle. By enclosing the blade on both sides, double edged blades can be used.
Ernest R. Emerson 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.

Robert Waldorf Loveless, a.k.a. Bob Loveless or RW Loveless, was an American knife maker who designed and popularized the hollowground drop point blade and the use of full tapered tangs and screw-type handle scale fasteners within the art of knifemaking. He is cited by other knifemakers and collectors as one of the most innovative custom knife makers in the world.
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.
Imperial Schrade Corp. was an American knife manufacturer of hunting knives, pocketknives, utility knives, and bayonets during the 20th and early 21st centuries.
