Penknife
Penknife, or pen knife, is a British English term for a small folding knife. Today the word ''penknife'' is the common British English term for both a pocketknife, which can have single or multiple blades, and for multi-tools, with additional tools incorporated into the design. Originally, penknives were used for thinning and pointing quills (cf. ''penna'', Latin for ''feather'') to prepare them for use as dip pens and, later, for repairing or re-pointing the nib. A penknife might also be used to sharpen a pencil, prior to the invention of the pencil sharpener. In the mid-1800s, penknives were necessary to slice the uncut edges of newspapers and books. A penknife did not necessarily have a folding blade, but might resemble a scalpel or chisel by having a short, fixed blade at the end of a long handle. One popular (but incorrect) folk etymology makes an association between the size of a penknife and that of a small ballpoint pen. During the 20th century there has been a proli ...

Bolster (knife)
A kitchen knife is any knife that is intended to be used in food preparation. While much of this work can be accomplished with a few general-purpose knives – notably a large chef's knife, a toughness, tough cleaver, a small #Paring, paring knife and some sort of serrated blade (such as a bread knife or serrated utility knife) – there are also many specialized knives that are designed for specific tasks. Kitchen knives can be made from several different materials. Construction Material * Carbon steel is an alloy of iron and carbon, often including other elements such as vanadium and manganese. Carbon steel commonly used in knives has around 1.0% carbon (ex. American Iron and Steel Institute, AISI 1095), is inexpensive, and holds its edge well. Carbon steel is normally easier to resharpen than many stainless steels, but is vulnerable to rust and stains. The blades should be cleaned, dried, and lubricated after each use. New carbon-steel knives may impart a metallic or "iron" ...

Industrial Revolution
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power and water power, the development of machine tools and the rise of the mechanized factory system. Output greatly increased, and a result was an unprecedented rise in population and in the rate of population growth. Textiles were the dominant industry of the Industrial Revolution in terms of employment, value of output and capital invested. The textile industry was also the first to use modern production methods. The Industrial Revolution began in Great Britain, and many of the technological and architectural innovations were of British origin. By the mid-18th century, Britain was the world's leadi ...

Spring (device)
A spring is an elastic object that stores mechanical energy. In everyday use the term often refers to coil springs, but there are many different spring designs. Modern springs are typically manufactured from spring steel, although some non-metallic objects like the bow are also springs. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length (this approximation breaks down for larger deflections). The ''rate'' or ''spring constant'' of a spring is the change in the force it exerts, divided by the change in deflection of the spring. That is, it is the gradient of the force versus deflection curve. An extension or compression spring's rate is expressed in units of force divided by distance, for example or N/m or lbf/in. A torsion spring is a spring that works by twisting; when it is twisted about its axis by an angle, it produc ...

Opinel
The Opinel company has manufactured and marketed a line of eponymous wooden-handled knives since 1890 from its headquarters in Saint-Jean-de-Maurienne, Savoie, France where the family-run company also operates a museum dedicated to its knives. The company sells approximately 15 million knives annually. Opinel knives are made of both high carbon and stainless steel, the latter being Sandvik steel from Sweden. Originally sold as a working man's knife, an Opinel knife has become emblematic of French culture. C NEWS, Le Couteau Opinel, La Lame Universelle', Directsoir, no 233, 30 october 2007, republished 7 July 2013, retrieved 15 May 2022 Pablo Picasso is said to have used one of the company's knives as a sculpting tool.

Sheffield, England
Sheffield is a city in South Yorkshire, England, whose name derives from the River Sheaf which runs through it. The city serves as the administrative centre of the City of Sheffield. It is historically part of the West Riding of Yorkshire and some of its southern suburbs were transferred from Derbyshire to the city council. It is the largest settlement in South Yorkshire. The city is in the eastern foothills of the Pennines and the valleys of the River Don with its four tributaries: the Loxley, the Porter Brook, the Rivelin and the Sheaf. Sixty-one per cent of Sheffield's entire area is green space and a third of the city lies within the Peak District national park. There are more than 250 parks, woodlands and gardens in the city, which is estimated to contain around 4.5 million trees. The city is south of Leeds, east of Manchester, and north of Nottingham. Sheffield played a crucial role in the Industrial Revolution, with many significant inventions and technol ...

Penny Knife
The penny knife was a originally a simple 18th century utility knife with a fixed blade. It got the name ''penny knife'' because it cost 1 penny in England and America towards the end of the 18th century. The famous ''Fuller's Penny Knife'' helped gain the reputation of Sheffield, England, cutlers in the pre-industrial era of the early 18th century. Description The ''penny knife'' later evolved into a basic, mass-produced pocketknife with a folding blade, which pivoted freely in and out of the handle without a backspring or other device to hold it in position (other than the frictional pressures of the knife handle). This type of knife was popular with farmers in the United States, England, France, Italy, Portugal, and Spain for much of the 19th and part of the 20th century, and consequently is often called a ''farmer knife'', ''sodbuster knife'', or ''peasant knife''.''The Youth's Companion'', Boston, MA: Perry Mason & Co., Vol. 52, No. 1 (2 January 1879), p. 108 Antique pen ...
