A plotter is a machine that produces vector graphics drawings. Plotters draw lines on paper using a pen, or in some applications, use a knife to cut a material like vinyl or leather. In the latter case, they are sometimes known as a cutting plotter.
A rain gauge is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over a predefined area, over a period of time. It is used to determine the depth of precipitation that occurs over a unit area and measure rainfall amount.
A knitting needle or knitting pin is a tool in hand-knitting to produce knitted fabrics. They generally have a long shaft and taper at their end, but they are not nearly as sharp as sewing needles. Their purpose is two-fold. The long shaft holds the active (unsecured) stitches of the fabric, to prevent them from unravelling, whereas the tapered ends are used to form new stitches. Most commonly, a new stitch is formed by inserting the tapered end through an active stitch, catching a loop of fresh yarn and drawing it through the stitch; this secures the initial stitch and forms a new active stitch in its place. In specialized forms of knitting the needle may be passed between active stitches being held on another needle, or indeed between/through inactive stitches that have been knit previously.
A scalpel, lancet, or bistoury is a small and extremely sharp bladed instrument used for surgery, anatomical dissection, podiatry and various handicrafts. A lancet is a double-edged scalpel.
A perforation is a small hole in a thin material or web. There is usually more than one perforation in an organized fashion, where all of the holes collectively are called a perforation. The process of creating perforations is called perforating, which involves removing bits of the workpiece with a tool. Old-fashioned lick-and-stick postage stamps are perforated. When a tool makes small cuts in the material it is called 'rouletting', because that tool often resembles a roulette wheel, with blades around the edge. Raffle tickets are a good example of rouletting.
A blade is the sharp, cutting portion of a tool, weapon, or machine, specifically designed to puncture, chop, slice, or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are intended to cut. This includes early examples made from flaked stones like flint or obsidian, evolving through the ages into metal forms like copper, bronze, and iron, and culminating in modern versions made from steel or ceramics. Serving as one of humanity's oldest tools, blades continue to have wide-ranging applications, including in combat, cooking, and various other everyday and specialized tasks.
Tweezers are small hand tools used for grasping objects too small to be easily handled with the human fingers. Tweezers are thumb-driven forceps most likely derived from tongs used to grab or hold hot objects since the dawn of recorded history. In a scientific or medical context, they are normally referred to as just "forceps", a name that is used together with other grasping surgical instruments that resemble pliers, pincers and scissors-like clamps.
Plastic welding is welding for semi-finished plastic materials, and is described in ISO 472 as a process of uniting softened surfaces of materials, generally with the aid of heat. Welding of thermoplastics is accomplished in three sequential stages, namely surface preparation, application of heat and pressure, and cooling. Numerous welding methods have been developed for the joining of semi-finished plastic materials. Based on the mechanism of heat generation at the welding interface, welding methods for thermoplastics can be classified as external and internal heating methods, as shown in Fig 1.
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 tough cleaver, a small paring knife and some sort of serrated blade – there are also many specialized knives that are designed for specific tasks. Kitchen knives can be made from several different materials.
Wine accessories are things that may be used in the storage or serving of wine. Wine accessories include many items such as wine glasses, corkscrews, and wine racks.
A toy balloon or party balloon is a small balloon mostly used for decoration, advertising and as a toy. Toy balloons are usually made of rubber or aluminized plastic and inflated with air or helium. They come in a great variety of sizes and shapes but are most commonly 10 to 30 centimetres in diameter. Toy balloons are not considered to include "sky lanterns", although these too are or were used as child toys in some parts of the world.
Lamy is a German pen manufacturing company founded in 1930 by Josef Lamy, a former sales representative for Parker Pen. The company acquired the Orthos pen manufacturer to begin production. Lamy is known for its innovative use of materials, particularly molded synthetic plastics in their pen designs.
CardTalk is an inexpensive cardboard phonograph for playing recordings, mainly voice, made on vinyl records. The name was used by Global Recordings Network, a Christian missionary movement which used the device from the 1960s to play religious talks in remote parts of the world that did not have electricity. It consists of a flat piece of cardboard creased and folded into a triangle. The base has a nub to hold the record in place. The upper "arm" forms the apex of the triangle and has a needle which is placed upon the record. The record is spun using a small pointed object like a pencil. The cardboard picks up the impressions on the record and vibrates loud enough to be heard causing the "card" to "talk". Several cardboard phonograph playing devices were patented around the same period and these include Jauquet (1953) for a "Pocket Speaking Device", J.S. Wiener's "Sound Emitting Device" (1967) and the "Record Player" of Max Meier-Maletz (1972).
Induction sealing is the process of bonding thermoplastic materials by induction heating. This involves controlled heating an electrically conducting object by electromagnetic induction, through heat generated in the object by eddy currents.
A glass cutter is a tool used to make a shallow score in one surface of a piece of glass that is to be broken in two pieces, for example to fit a window. The scoring makes a split in the surface of the glass which encourages the glass to break along the score. This is not to be confused with the tools used to make cut glass objects.
Hairstyling tools may include hair irons, hair dryers, hairbrushes, hair rollers, diffusers and various types of scissors.
Drafting tools may be used for measurement and layout of drawings, or to improve the consistency and speed of creation of standard drawing elements. Tools such as pens and pencils mark the drawing medium. Other tools such as straight edges, assist the operator in drawing straight lines, or assist the operator in drawing complicated shapes repeatedly. Various scales and the protractor are used to measure the lengths of lines and angles, allowing accurate scale drawing to be carried out. The compass is used to draw arcs and circles. A drawing board was used to hold the drawing media in place; later boards included drafting machines that sped the layout of straight lines and angles. Tools such as templates and lettering guides assisted in the drawing of repetitive elements such as circles, ellipses, schematic symbols and text. Other auxiliary tools were used for special drawing purposes or for functions related to the preparation and revision of drawings. The tools used for manual technical drawing have been displaced by the advent of computer-aided drawing, drafting and design (CADD).
Puncture resistance denotes the relative ability of a material or object to inhibit the intrusion of a foreign object. This is defined by a test method, regulation, or technical specification. It can be measured in several ways ranging from a slow controlled puncture to a rapid impact of a sharp object or a rounded probe.
Telekinesis is a hypothetical psychic ability allowing an individual to influence a physical system without physical interaction. Experiments to prove the existence of telekinesis have historically been criticized for lack of proper controls and repeatability. There is no reliable evidence that telekinesis is a real phenomenon, and the topic is generally regarded as pseudoscience.
The 3Doodler is a 3D pen developed by Peter Dilworth, Maxwell Bogue, and Daniel Cowen of WobbleWorks, Inc.. The 3Doodler works by extruding heated plastic that cools almost instantly into a solid, stable structure, allowing for the free-hand creation of three-dimensional objects. It utilizes plastic thread made of either acrylonitrile butadiene styrene ("ABS"), polylactic acid ("PLA"), or “FLEXY”, thermal polyurethane (“TPU”) that is melted and then cooled through a patented process while moving through the pen, which can then be used to make 3D objects by hand. The 3Doodler has been described as a glue gun for 3D printing because of how the plastic is extruded from the tip, with one foot of the plastic thread equaling "about 11 feet of extruded material".
