The router is a power tool with a flat base and a rotating blade extending past the base. The spindle may be driven by an electric motor or by a pneumatic motor. It routs an area in hard material, such as wood or plastic. Routers are used most often in woodworking, especially cabinetry. They may be handheld or affixed to router tables. Some woodworkers consider the router one of the most versatile power tools.
Hydraulic rescue tools, also known as jaws of life, are used by emergency rescue personnel to assist in the extrication of victims involved in vehicle accidents, as well as other rescues in small spaces. These tools include cutters, spreaders, and rams. Such devices were first used in 1963 as a tool to free race car drivers from their vehicles after crashes.
A hand axe is a prehistoric stone tool with two faces that is the longest-used tool in human history. It is made from stone, usually flint or chert that has been "reduced" and shaped from a larger piece by knapping, or hitting against another stone. They are characteristic of the lower Acheulean and middle Palaeolithic (Mousterian) periods, roughly 1.6 million years ago to about 100,000 years ago, and used by Homo erectus and other early humans, but rarely by Homo sapiens.
A peeler is a kitchen tool, a distinct type of kitchen knife, consisting of a metal blade with a slot with a sharp edge attached to a handle, used to remove the outer layer of some vegetables such as potatoes, broccoli stalks, and carrots, and fruits such as apples and pears. A paring knife may also be used to peel vegetables. The blade of a peeler has a slot with one side sharpened; the other side of the slot prevents the blade from cutting too far into the vegetable.
A drill bit is a cutting tool used in a drill to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create different kinds of holes in many different materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the shank in the chuck.
A hand plane is a tool for shaping wood using muscle power to force the cutting blade over the wood surface. Some rotary power planers are motorized power tools used for the same types of larger tasks, but are unsuitable for fine-scale planing, where a miniature hand plane is used.
A pencil sharpener is a tool for sharpening a pencil's writing point by shaving away its worn surface. Pencil sharpeners may be operated manually or by an electric motor. It is common for many sharpeners to have a casing around them, which can be removed for emptying the pencil shavings debris into a bin.
A pie chart is a circular statistical graphic which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice is proportional to the quantity it represents. While it is named for its resemblance to a pie which has been sliced, there are variations on the way it can be presented. The earliest known pie chart is generally credited to William Playfair's Statistical Breviary of 1801.
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 and a smaller serrated blade utility knife — there are also many specialized knives that are designed for specific tasks such as a tough cleaver, a small paring knife, and a bread knife. Kitchen knives can be made from several different materials, though the commonest is a hardened steel blade with a wooden handle.
A core sample is a cylindrical section of (usually) a naturally-occurring substance. Most core samples are obtained by drilling with special drills into the substance, such as sediment or rock, with a hollow steel tube, called a core drill. The hole made for the core sample is called the "core hole". A variety of core samplers exist to sample different media under different conditions; there is continuing development in the technology. In the coring process, the sample is pushed more or less intact into the tube. Removed from the tube in the laboratory, it is inspected and analyzed by different techniques and equipment depending on the type of data desired.
A modern core drill is a drill specifically designed to remove a cylinder of material, much like a hole saw. The material left inside the drill bit is referred to as the core.
A comparison of apples and oranges occurs when two items or groups of items are compared that cannot be practically compared, typically because of inherent or fundamental differences between the objects.
Gastrique is caramelized sugar, deglazed with vinegar or other sour liquids, used as a sweet and sour flavoring for sauces.
Whipped cream, also known as Chantilly cream or crème Chantilly, is high-fat dairy cream that has been aerated by whisking until it becomes light, fluffy, and capable of holding its shape. This process incorporates air into the cream, creating a semi-solid colloid. It is commonly sweetened with white sugar and sometimes flavored with vanilla. Whipped cream is often served on desserts and hot beverages, and used as an ingredient in desserts.
A baked apple is a dish consisting of an apple baked in an oven until it has become soft. The core is usually removed and the resulting cavity stuffed with sweet or savory fillings and seasonings. Pears and quinces may be prepared in the same way.
Grafting or graftage is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together. The natural equivalent of this process is inosculation. The technique is most commonly used in asexual propagation of commercially grown plants for the horticultural and agricultural trades. The scion is typically joined to the rootstock at the soil line; however, top work grafting may occur far above this line, leaving an understock consisting of the lower part of the trunk and the root system.
A cheese knife is a type of kitchen knife specialized for the cutting of cheese. Different cheeses require different knives, according primarily to hardness. There are also a number of other kitchen tools designed for cutting or slicing cheese, especially the harder types. These include the cheese cutter, cheese slicer, cheese plane, cheese scoop for soft cheese and others, collectively known as cheese servers.
A pineapple cutter is a hand-held cylindrical kitchen utensil with a circular blade at the end designed for cutting pineapples. A knife is required to open the top of the pineapple before using the pineapple cutter. The cutter will cut the flesh of the pineapple into a spiral and also removes the core. Different sizes are available so as not to cut into the skin of the pineapple or cause too much to be wasted.
Sirop de Liège is a Belgian jam or jelly-like spread. Apple and pear are principally used, often with dates: other fruit such as apricot can be used as well. Sugar and other sweeteners are not normally needed.
Ice drilling allows scientists studying glaciers and ice sheets to gain access to what is beneath the ice, to take measurements along the interior of the ice, and to retrieve samples. Instruments can be placed in the drilled holes to record temperature, pressure, speed, direction of movement, and for other scientific research, such as neutrino detection.
