Scourer

Scourer

Just try not to hurt your wrist when scouring your pots and pans.

  • Scourers are objects used on surfaces, often on food dishes like pots and pans, to clean or remove marks or food residue.
  • ‘Scourers’ are also known as ‘scouring pads’ and ‘scourer pads’, and historically, fine steel wool was, and is still used for scouring purposes, although it tends to disintegrate quickly.
  • The shape of scourers typically ranges from rectangular prisms in various heights, to rough, flexible flattened spheres or balls.
  • Modern scourers are generally made of coiled stainless steel, or plastic or steel mesh, and some are double sided with a softer sponge surface for gripping or wiping off residue.
  • An early scourer was invented by George Watson from Illinois, in the United States, in 1908; and it was designed in particular, to scour and wax a clothes iron.

  • The normal process of using a scourer requires the user to hold it in one’s hand, and continuously and firmly rub it on the surface to be cleaned, sometimes with the addition of water or cleaning solution.
  • The process of scouring can cause pain in the arm, wrist and hand, due to the constant scrubbing movement.
  • Scourers should not be used on surfaces that have a special coating, like non-stick pans and dishes, which can easily be scrubbed off.
  • A number of scourers were invented in the 1920s; and notable inventor Russell Kingman from New Jersey in the United States, filed some of the earliest patents for various scouring implements during that time, some of which our modern ones are based on.
  • Scouring can cause one’s skin to become irritated; and rubber gloves are often used to avoid or lessen the problem.

Seam Ripper

Seam Ripper

What are the true origins of a seam ripper?

  • Seam rippers are an item designed for breaking or undoing sewn stitches, often on seams.
  • A seam ripper is also known as a ‘stitch unpicker’, ‘quick unpic’ and a ‘quick unpick’.
  • Typically, seam rippers have two spokes, one sharp and the other blunt, connected by a handle, while the intersection is usually a sharp blade.
  • When using seam rippers, the sharp point is placed underneath the stitch and the device is pulled upwards, causing the thread to touch the blade and be cut by it; while the blunt or ball point is designed to protect the fabric that the tool comes in contact with.
  • Seam rippers where probably invented some time in the late 1800s, and one of the earliest patents for a similar tool was a thimble that had the addition of a small knife that was patented in the United States by W Miller in 1883, that was used to rip threads in a similar way; while a later patent exists for a tool designed for the sole purpose of ripping seams, in 1898 by John Fisher from Canada.

  • Seam rippers typically range from 7 to 15 centimetres (3 to 6 inches) in length and are held with one’s fingers.
  • Although its primary purpose is to cut stitches or open up a sew seam, seam rippers can also be used to undo threads or stitches that have been incorrectly placed.
  • Seam rippers generally come with a lid, or can be inserted into a case for safe storage.
  • Seam rippers can be used to slit open button holes; to easily trim small, excess material; or to detach buttons from fabric.
  • Seam rippers come in a variety of shapes and colours, and the blade is typically made of metal, and the usually have a wooden, plastic or metal handle.

Paper Knife

Paper Knife

One of the most decorated desk items – the paper knife.

  • A paper knife is an item used in a similar way to a typical knife, but is used to cut open folded papers, like envelopes and pages in a book.
  • ‘Paper knives’ are also known as ‘letter openers’, although originally they differed in appearance and purpose.
  • Paper knives typically consist of a blade and a handle, sometimes made of one material; and the blade is generally flat and blunt.
  • Paper knives became popular by the 1800s, when it became the norm to own the object as a standard desk item.
  • A paper knife commonly has a blade made from metal, like stainless steel, however the whole letter opener can also be made from ivory, wood or plastic, that is thinned out in the blade area to make it suitable for slitting paper.

  • Paper knives were used in Europe from the 1700s to open book pages that were not cut during the manufacturing process, and they replaced pen knives that were typically used to sharpen a quill, as pen knives would cut the paper inaccurately due to their very sharp blade.
  • Martin Luther King, Jr. was stabbed by Izola Curry, using a paper knife in 1958, ten years before he was assassinated, and the knife had to be surgically removed.
  • Paper knives were not used to open envelopes until the mid to late 1800s, and they were manufactured specifically for this purpose with a narrower and pointier blade than the original paper knives.
  • The handle of a paper knife is commonly ornamental, featuring an aesthetic pattern or sculptured depiction.
  • The primary concept of a paper knife has been translated into electronic machinery, that functions in much the same way.

Unmanned Aerial Vehicle

Unmanned Aerial Vehicle

What are your opinions on unmanned aerial vehicles?

  • Unmanned aerial vehicles are aircraft that are controlled remotely, and therefore do not carry any humans.
  • ‘Unmanned aerial vehicles’ are also known as ‘unpiloted aerial vehicles’, ‘unmanned aircraft’, ‘remotely piloted aircraft’, ‘drones’, ‘UAVs’, ‘UA’ and ‘RPA’, among others.
  • Early unmanned aerial vehicles were balloon bombs, manufactured in Europe’s Austria, and were used on Italy’s Venice during the middle of the 19th century; and in the early 20th century, drones were developed for use as target practice by the military.
  • Numerous countries have stated it is illegal to possess and fly unmanned aerial vehicles under normal circumstances, and government consent is usually required.
  • Unmanned aerial vehicles come in a variety of sizes and shapes, from small robots to life-sized aeroplanes, and they have been used during dangerous missions, such as rescue, to scout, or to broadcast, among others, and have been used extensively as military tools.

  • Large organisations, such as Google, Amazon, military groups and America’s Central Intelligence Agency, investigate and develop unmanned aerial vehicles for their organisation’s purposes.
  • In 2006, the United States were the leading manufacturers of unmanned aerial vehicles, producing more than 60% of the worldwide total, and the machines have become a popular choice for some purposes, due to their relatively low cost.
  • As of 2014, the longest flight time recorded of an unmanned aerial vehicle was 330 hours and 22 minutes, which is just over 14 days, and this world record was set by the ‘Zephyr’, which was built by a United Kingdom based company, QinetiQ.
  • It is against the law to shoot down unmanned aerial vehicles, however if a drone manages to damage something such as a kite, tethered balloon or other property, the offending drone company is liable to be sued.
  • Film producers, farmers, real estate agents and some lawyers, among others, have shown particular interest in commercial unmanned aerial vehicles, however use of drones for various purposes requires a legal framework to operate under, especially regarding privacy laws, and legislation concerning their use is yet to be passed in some countries.

Crochet Hook

Crochet Hook

Crocheting without a crochet hook must have been pretty difficult.

  • A crochet hook is a tool used in the art and craft of crocheting, and the tool is manipulated with one’s hand to make a series of loops from yarn, thread or other fibres, to create fabric or cord.
  • ‘Crochet hooks’ are also known as ‘crochet needles’ and the word ‘crochet’ is a French word that comes from the Old Norse word ‘krókr‘ meaning ‘hook’.
  • Crochet hooks are typically long and stick like with a hooked end, and sometimes they have a handle for better comfort and/or grip.
  • Crochet hooks come in a variety of sizes and thicknesses, with at least 25 different sizes that are graded using letters or numbers.
  • Crochet hooks can be used in knitting to pick up dropped stitches, and for other craft purposes, and they can also be used to maintain hair dreadlocks.

  • Crochet hooks can be held like a knife or a pencil, although one technique is not necessarily better than the other, and it comes down to personal preference as to which is used.
  • Crochet hooks were most likely invented in the early 1800s, and first made of wire, and possibly originated in Ireland, Europe.
  • Some unique versions of crochet hooks include the much longer Tunisian hook, used in Tunisian crochet; and the cro-hook, used for double-sided crochet, that is particularly effective using two different colours of yarn.
  • Crochet hooks are typically made of plastic, wood, or aluminium, and originally they were made of steel, bone, ivory, and other materials.
  • It is common that only a single crochet hook is used in the practice of crochet, and it can be used in either the left or right hand, depending the user’s dominant hand.

Towel

Towel

As author Douglas Adams said, towels are the one of the most useful items.

  • Towels are a textile item commonly used to remove and collect moisture, often water, from an object.
  • Towels are generally used by being placed on an object, and are typically pressed and rubbed for maximum effect.
  • Towels are most often made of absorbent material like cotton, bamboo, paper, synthetic fibres or other textiles, and the fabric often has a looped pile and is known as ‘terry cloth’.
  • The size of towels generally range between 30 x 61 centimetres to 76 x 152 centimetres (12 x 24 inches to 30 x 60 inches), although smaller and larger ones are available, and they are usually rectangular in shape.
  • Towels are commonly used after showering or bathing to dry oneself or one’s hands, and they can also be used for, but are not limited to, drying dishes and kitchen items, by sports enthusiasts to remove perspiration, at the beach to lay on, or for decorative purposes.

  • Towels are often dyed a single colour, although imagery or patterns can be imprinted or woven in, and other decorative features can also be included.
  • Until the availability of mass production machinery in the 1800s, towels were uncommon, due to being time-consuming to make, and as a result, expensive.
  • Towels are generally made by machines that spin, warp, weave, bleach and dye the material, as well as package the product.
  • It is said that towels were invented in Turkey, in the Middle East, and they were originally light and sheet-like.
  • Annually, on the 25th of May, National Towel Day is observed in some countries.
