Quern-stones

Quern-stones are stone tools for hand-grinding a wide variety of materials. They were used in pairs. The lower, stationary, stone is called a quern, while the upper mobile stone is called a handstone. They were first used in the Neolithic to grind cereals into flour.

güiro

The güiro is a Latin-American percussion instrument consisting of an open-ended, hollow gourd with parallel notches cut in one side. It is played by rubbing a stick or tines along the notches to produce a ratchet-like sound.
The güiro is commonly used in Puerto Rican and other Latin-American music, and plays a key role in the typical rhythm section of important genres like cumbia and son. Playing the güiro usually requires both long and short sounds, made by scraping up and down in long or short strokes.
The güiro, like the maracas, is often played by a singer. Another type of güiro, commonly found in Brazil, is the reco-reco, is made of a cylindrical metal box that encases two or three steel springs. These are stretched over a lid, against which a metal stick is rubbed.

corf

A corf (pl. corves) or corve (pl. corves) is a basket of net, chicken wire or similar materials, used to contain live fish or crustaceans (such as crayfish) underwater, at docks or in fishing boats. Corfs were used formerly to keep captured or grown fish live and fresh for consumption. Today, corfs used this purpose have commonly been replaced by refrigeration and freezing.

The word in mining also meant a small wagon for carrying coal, ore, etc., or a wicker basket formerly used for this purpose.

strop

strop (third-person singular simple present strops, present participle stropping, simple past and past participle stropped)

1. (obsolete) To strap.
2. (recorded since 1842; now most used) To hone (a razor) with a strop.

pantograph

A pantograph (from Greek roots παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical movements in a second pen. If a line drawing is traced by the first point, an identical, enlarged, or miniaturized copy will be drawn by a pen fixed to the other.

Because of their effectiveness at translating motion in a controlled fashion, pantographs have come to be used as a type of motion guide for objects large and small. A common example of the use of a pantograph assembly as mechanical guide frame is the extension arm of an adjustable wall-mounted mirror.

rapidograph

A technical pen is a specialized instrument used by an engineer, architect, or drafter to make lines of constant width for architectural, engineering, or technical drawings. It has been also generally called "rapidograph", although that particular name is officially a trademarked line of products made by German company Rotring, and by American manufacturer Chartpak, Inc. when they purchased the rights from Rotring to produce the pens in the USA under the Koh-I-Noor brand.

Most technical pens use ink cartridges which can be refilled or replaced.

stylus

A stylus (plural: styli or styluses) is a writing utensil, or a small tool for some other form of marking or shaping, for example in pottery. The word is also used for a computer accessory that is used to assist in navigating with resistive touchscreens. It usually refers to a narrow elongated staff, similar to a modern ballpoint pen. Many styli are heavily curved to be held more easily. Another widely-used writing tool is the stylus used by blind users in conjunction with the slate for punching out the dots in Braille.

mandrel

A mandrel (also mandril or arbor) is one of the following:

• an object used to shape machined work.
• a tool component that grips or clamps materials to be machined.
• a tool component that can be used to grip other moving tool components.

Gaffer tape

Gaffer tape, gaffer's tape, gaff tape or gaffa tape is a strong, tough, cotton cloth pressure sensitive tape with strong adhesive properties. It is used in theater, film and television productions as well as during live performances and any other kind of stage work. While related to duct tape, it differs in that it can be removed cleanly because it uses a synthetic rubber adhesive rather than a natural rubber adhesive. The tape is often referred to as a production expendable because it is discarded after the production process is complete.

anemometer

An anemometer is a device for measuring wind speed, and is a common weather station instrument. The term is derived from the Greek word anemos, meaning wind. The first known description of an anemometer was given by Leon Battista Alberti around 1450.

Anemometers can be divided into two classes: those that measure the wind's speed, and those that measure the wind's pressure; but as there is a close connection between the pressure and the speed, an anemometer designed for one will give information about both.

Sawzall

A reciprocating saw is a type of saw in which the cutting action is achieved through a push and pull reciprocating motion of the blade.

The term reciprocating saw is commonly assigned to a type of saw used in construction and demolition work. This type of saw, also known as a recipro saw, Sabre Saw, or Sawzall (a trademark of the Milwaukee Electric Tool Company) has a large blade resembling that of a Jigsaw and a handle oriented to allow the saw to be used comfortably on vertical surfaces. The typical style of this saw has a foot at the base of the blade, also similar to a jigsaw. The user rests this foot against the surface being cut so that the tendency of the blade to push away from or pull towards the cut as the blade travels through its cycle can be countered.

Pentalobe

Pentalobe:

A fastener interface with five rounded lobes.

cajón

A cajón (Spanish: 'crate', 'drawer', or 'box') is a kind of box drum played by slapping the front face (generally thin plywood) with the hands.

Pinking shears

Pinking shears are scissors, the blades of which are sawtoothed instead of straight. Pinking shears leave a zigzag pattern instead of a straight edge.

Pinking shears have a utilitarian function for cutting woven cloth. Cloth edges that are unfinished will easily fray, the weave becoming undone and threads pulling out easily. The sawtooth pattern does not prevent the fraying but limits the length of the frayed thread and thus minimizes damage.

Hame

Hames, a pair of curved metal (or sometimes wooden) pieces lying on the horse collar of a horse harness, taking the pull from the traces

bumpershoot

bumpershoot: A whimsical term for an umbrella.

holesaw

A hole saw (also styled as holesaw) is a saw that is in the shape of a circle. It is used in a drill to cut large holes in reasonably thin material.

Holesaws have the same general mechanical construction as the diamond core drill bit, but, instead of the abrasive effect of diamonds, the holesaw uses the cutting effect of saw teeth. The open end of the saw's cylinder is milled with saw teeth. Instead of masonry, the holesaw is suitable for cutting wood, plastic, soft plaster or soft metal.

The placement of the saw teeth makes the cut annulus slightly wider than the cylinder wall thickness, so the cylinder doesn't rub in the cut. Just as in the diamond core drill bit, the cylinder is mounted on a mandrel — an arbor with a centre pilot drill — and has sloping slots to clear sawdust.

Gravettian

The Gravettian toolmaking culture was a specific archaeological industry of the European Upper Palaeolithic era prevalent before the last glacial epoch. It is named after the type site of La Gravette in the Dordogne region of France where it's characteristic tools were first found and studied. It dates from between 28,000 and 22,000 years ago and where found, succeeded the artifacts datable to the Aurignacian culture.

The diagnostic characteristic artifacts of the industry are small pointed restruck blade with a blunt but straight back, a carving tool known as a Noailles burin. (See to compare with similar purposed modern tool: burin)

Artistic achievements of the Gravettian cultural stage include the hundreds of Venus figurines, which are widely distributed in Europe. The industry had counterparts across central Europe and into Russia, as did the predecessor culture, which is also linked to similar figurines and carvings.

Impeller

An impeller is a rotor inside a tube or conduit to increase the pressure and flow of a fluid.

Auger

An auger is a device for moving material or liquid (see Archimedes' screw) by means of a rotating helical flighting. The material is moved along the axis of rotation. For some uses the helical 'flighting' is enclosed in a tube, for other uses the flighting is not encased. An integral part of a drill, the auger of the drill bit uses this mechanism to remove shavings from the hole being drilled.
