Hand Saws
In woodworking and carpentry, hand saws, also known as "panel saws", are used to cut pieces of wood into different shapes. This is usually done in order to join the pieces together and carve a wooden object. They operate by having a series of sharp points, called teeth, of a substance that is harder than the wood being cut. Hand saws have been used for thousands of years. Egyptian hieroglyphics exist depicting ancient woodworkers sawing boards into pieces, and ancient bow saws have been found in Japan. Cut patterns on ancient boards are occasionally observed to bear the unique cutting marks left by saw blades, particularly if the wood was not 'smoothed up' by some method. Twenty-four saws from eighteenth-century England are currently preserved.Olmert, Michael (1996). ''Milton's Teeth and Ovid's Umbrella: Curiouser & Curiouser Adventures in History'', p.178. Simon & Schuster, New York. . Materials for saw blades have varied over the ages. Bronze saws were likely used before ste ...

Crosscut Saw
A crosscut saw (thwart saw) is any saw designed for cutting wood perpendicular to (across) the wood grain. Crosscut saws may be small or large, with small teeth close together for fine work like woodworking or large for coarse work like log bucking, and can be a hand tool or power tool. The cutting edge of each tooth is angled in an alternating pattern. This design allows each tooth to act like a knife edge and slice through the wood in contrast to a rip saw, which tears along the grain, acting like a miniature chisel. Some crosscut saws use special teeth, called ''rakers'', designed to clean out the cut strips of wood from the ''kerf''. Crosscut saws generally have smaller teeth than rip saws. Some saws, such as Japanese saws and those used by the ancient Egyptians, are designed to cut only on the pull stroke. Western saws, on the other hand, are designed to cut on the push stroke. Cross cut saws designed for log bucking and tree felling are designed to cut on the pull strok ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knife
A knife (: knives; from Old Norse 'knife, dirk') is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least Stone Age, 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone (such as flint and obsidian), over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin. Knives can serve various purposes. Hunters use a hunting knife, soldiers use the combat knife, scouts, campers, and hiking, hikers carry a pocketknife; there are kitchen knives for preparing foods (the chef's knife, the paring knife, bread knife, cleaver), table knife (butter knives and steak knives), weapons (daggers or switchblades), knives for throwing o ...

Saws
A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge used to cut through material. Various terms are used to describe toothed and abrasive saws. Saws began as serrated materials, and when mankind learned how to use iron, it became the preferred material for saw blades of all kinds. There are numerous types of hand saws and mechanical saws, and different types of blades and cuts. Description A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. Terminology A number of terms are used to describe saws. Kerf The narrow channel left behind by the saw and (relatedly) the measure of its width is known as the kerf. As such, it also refers to the wasted material that is turned into sawdust, and becomes a factor in measurements when making cuts. For example, cutting an 8-foot (2.4 meter) piece of wood into 1 foot (30 cm) sect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Tools
A hand tool is any tool that is powered by hand rather than a motor. Categories of hand tools include wrenches, pliers, cutters, files, striking tools, struck or hammered tools, screwdrivers, vises, clamps, snips, hacksaws, drills, and knives. Outdoor tools such as garden forks, pruning shears, and rakes are additional forms of hand tools. Portable power tools are not hand tools. History Hand tools have been used by humans since the Stone Age, when stone tools were used for hammering and cutting. During the Bronze Age, tools were made by casting alloys of copper and tin. Bronze tools were sharper and harder than those made of stone. During the Iron Age iron replaced bronze, and tools became even stronger and more durable. The Romans developed tools during this period which are similar to those being produced today. After the Industrial Revolution, most tools were made in factories rather than by craftspeople. A large collection of British hand tools dating fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saw Set
A saw set is a tool or part of the tool kit for tuning saw blades. It adjusts the ''set'', or distance the saw tooth is bent away from the saw blade. The magnitude of set determines the cut width and prevents the blade of the saw from binding in the wood. Many different manual and automated saw sets have been developed since at least the 19th century. Purpose When the teeth of a saw are formed from the body, they are in line and the same thickness as the blade immediately behind them. A saw with this configuration is described as having 'no' or '0' set. To prevent the body of the blade binding and for other enhancements to the cutting action, the teeth can be set (angled out) from the blade. Teeth can be set in several patterns: single-sided set, alternating set or a patterned set. Most Western and Asian handsaws use an alternating set, whereby a tooth is set the opposite direction from the preceding one. Specialized tools like veneer saws or flush-cut saws may be set only to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musical Saw
A musical saw, also called a singing saw, is a hand saw used as a musical instrument. Capable of continuous glissando (portamento), the sound creates an ethereal tone, very similar to the theremin. The musical saw is classified as a plaque friction idiophone with direct friction (132.1) under the Hornbostel-Sachs system of musical instrument classification, and as a metal sheet played by friction (151) under the revision of the Hornbostel-Sachs classification by the MIMO Consortium. Playing The saw is generally played seated with the handle squeezed between the legs, and the far end held with one hand. Some sawists play standing, either with the handle between the knees and the blade sticking out in front of them. The saw is usually played with the serrated edge, or "teeth", facing the body, though some players face them away. Some saw players file down the teeth, which makes no discernable difference to the sound. Manyespecially professionalsaw players use a handle, called a ...

Basque Rural Sports
Basque rural sports, known as ''Deportes Rurales'' in Spanish language, Spanish or ''Herri Kirolak'' in Basque language, Basque, is the term used for a number of sports competitions rooted in the traditional lifestyles of the Basque people. The term ''force basque'' is used in French language, French. Virtually all regional Basque rural sports have their origin in the two main historical occupations, the ''baserritarra'' (farmer) and ' (fisher), with a larger percentage hailing from the rural background. The Social change, sociological changes in the Basque Country (historical territory), Basque Country have led many of these becoming technically obsolete in the 19th and 20th century. Few continue to exist as rural or marine activities connected to everyday life and have become rare but many have managed to transform themselves into popular sports instead, some of which have become extremely popular. Winners receive a Basque beret (' or ') as a trophy, hence the Basque word for " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rural Sport
In general, a rural area or a countryside is a geographic area that is located outside towns and cities. Typical rural areas have a low population density and small settlements. Agricultural areas and areas with forestry are typically described as rural, as well as other areas lacking substantial development. Different countries have varying definitions of ''rural'' for statistical and administrative purposes. Rural areas have unique economic and social dynamics due to their relationship with land-based industry such as agriculture, forestry, and resource extraction. Rural economics can be subject to boom and bust cycles and vulnerable to extreme weather or natural disasters, such as droughts. These dynamics alongside larger economic forces encouraging urbanization have led to significant demographic declines, called rural flight, where economic incentives encourage younger populations to go to cities for education and access to jobs, leaving older, less educated and less wea ...

Australians
Australians, colloquially known as Aussies, are the citizenship, citizens, nationality, nationals and individuals associated with the country of Australia. This connection may be residential, legal, historical or ethno-cultural. For most Australians, these connections exist and are collectively the source of their being Australian. Australian law does not provide for any racial or ethnic component of nationality, instead relying on Australian nationality law, citizenship as a legal status, though the Constitutional framers considered the Commonwealth to be "a home for Australians and the British race alone", as well as a "Christian Commonwealth". Since the postwar period, Australia has pursued an official policy of multiculturalism and has the List of sovereign states and dependent territories by immigrant population, world's eighth-largest immigrant population, Immigration to Australia, with immigrants accounting for 30 percent of the population in 2019.

Basque People
The Basques ( or ; ; ; ) are a Southwestern European ethnic group, characterised by the Basque language, a common culture and shared genetic ancestry to the ancient Vascones and Aquitanians. Basques are indigenous to, and primarily inhabit, an area traditionally known as the Basque Country ()—a region that is located around the western end of the Pyrenees on the coast of the Bay of Biscay and straddles parts of north-central Spain and south-western France. Etymology The English word ''Basque'' may be pronounced or and derives from the French ''Basque'' (), itself derived from Gascon ''Basco'' (pronounced ), cognate with Spanish ''Vasco ''(pronounced ). Those, in turn, come from Latin ''Vascō'' (pronounced ; plural '' Vascōnēs''—see history section below). The Latin generally evolved into the bilabials and in Gascon and Spanish, probably under the influence of Basque and the related Aquitanian (the Latin /w/ instead evolved into in French, Ita ...

Chisel
A chisel is a hand tool with a characteristic Wedge, wedge-shaped cutting edge on the end of its blade. A chisel is useful for carving or cutting a hard material such as woodworking, wood, lapidary, stone, or metalworking, metal. Using a chisel involves forcing the blade into some material to cut it. The driving force may be applied by pushing by hand, or by using a mallet or hammer. In industrial use, a hydraulic ram or falling weight ('trip hammer') may be used to drive a chisel into the material. A Chisel#Gouge, gouge is a type of chisel that serves to carve small pieces from the material; particularly in woodworking, woodturning and sculpture. Woodworking Woodworking chisels range from small hand tools for tiny details, to large chisels used to remove big sections of wood, in 'roughing out' the shape of a pattern or design. Typically, in Wood carving, woodcarving, one starts with a larger tool, and gradually progresses to smaller tools to finish the detail. One of t ...

Rip Saw
A ripsaw (or rip saw) is a wood saw that is specially designed for making a rip cut, a cut made parallel to the direction of the wood grain. Design The cutting edge of each tooth has a flat front edge and it is angled backward by about 8°, in contrast to a crosscut saw, which has teeth angled backward by about 15°. With the "rip" tooth pattern, the edges are sharpened at right angles to the cutting plane, forming chisel-like cutting surfaces, whereas crosscut teeth are sharpened at an angle, so that each tooth has a knife-like cutting point in contact with the wood. This design keeps the saw from following grain lines, which could curve the path of the saw: by acting like a chisel, the saw can more easily cut across deviating grain lines, which is necessary if a straight cut is to be achieved. This feature enables the orthogonal cutting edge to efficiently transport wood-chips from the kerf, allowing subsequent teeth to perform a more effective cut. It is possible to se ...
