Karabiner
A carabiner or karabiner (), often shortened to biner or to crab, colloquially known as a (climbing) clip, is a specialized type of shackle, a metal loop with a spring-loaded gate used to quickly and reversibly connect components, most notably in safety-critical systems. The word comes from the German , short for , meaning "carbine hook," as the device was used by carabiniers to attach their carbines to their belts. Use Carabiners are widely used in rope-intensive activities such as climbing, fall arrest systems, arboriculture, caving, sailing, hot-air ballooning, rope rescue, construction, industrial rope work, window cleaning, whitewater rescue, and acrobatics. They are predominantly made from both steel and aluminium. Those used in sports tend to be of a lighter weight than those used in commercial applications and rope rescue. Often referred to as carabiner-style or as mini-carabiners, carabiner keyrings and other light-use clips of similar style and design have also ...

Carbine
A carbine ( or ) is a long gun that has a barrel shortened from its original length. Most modern carbines are rifles that are compact versions of a longer rifle or are rifles chambered for less powerful cartridges. The smaller size and lighter weight of carbines make them easier to handle. They are typically issued to high-mobility troops such as special operations soldiers and paratroopers, as well as to mounted, artillery, logistics, or other non-infantry personnel whose roles do not require full-sized rifles, although there is a growing tendency for carbines to be issued to front-line soldiers to offset the increasing weight of other issued equipment. An example of this is the M4 carbine, the standard issue carbine of the United States Armed Forces. Etymology The name comes from its first users — cavalry troopers called " carabiniers", from the French ''carabine'', from Old French ''carabin'' (soldier armed with a musket), whose origin is unclear.

Carabinier
A carabinier (also sometimes spelled carabineer or carbineer) is in principle a soldier armed with a carbine, musket, or rifle, which became commonplace by the beginning of the Napoleonic Wars in Europe. The word is derived from the identical French language, French word ''wikt:carabinier#French, carabinier''. Historically, carabiniers were generally (but not always) Cavalry, horse soldiers. The carbine was considered a more appropriate firearm for a horseman than a full-length musket, since it was shorter in length, weighed less, and was easier to manipulate on horseback. Light infantry sometimes carried carbines because they are less encumbering when moving rapidly, especially through vegetation, but in most armies the tendency was to equip light infantry with longer-range weapons such as rifles rather than shorter-range weapons such as carbines. In Italy and Spain, carbines were considered suitable equipment for soldiers with policing roles, so the term ''carabinier'' evolved ...

Kilonewton
The newton (symbol: N) is the unit of force in the International System of Units (SI). Expressed in terms of SI base units, it is 1 kg⋅m/s2, the force that accelerates a mass of one kilogram at one metre per second squared. The unit is named after Isaac Newton in recognition of his work on classical mechanics, specifically his second law of motion. Definition A newton is defined as 1 kg⋅m/s2 (it is a named derived unit defined in terms of the SI base units). One newton is, therefore, the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force. The units "metre per second squared" can be understood as measuring a rate of change in velocity per unit of time, i.e. an increase in velocity by one metre per second every second. In 1946, the General Conference on Weights and Measures (CGPM) Resolution 2 standardized the unit of force in the MKS system of units to be the amount needed t ...

Threaded Sleeve
A maillon, maillon rapide or quick link is a metal link, similar to a carabiner. Maillons have a threaded sleeve which tightens over a thread, as opposed to a hinged gate like a carabiner, making them stronger, but more difficult to use. Like carabiners, maillons are available in a range of shapes and thicknesses (i.e., strengths), and often offer greater versatility over carabiners as their different shapes and lack of hinged gates allow them to be used in multi-directional load situations. The word ''maillon'' comes from the French language, meaning "link". Usage Maillons are used primarily in climbing and caving. In caving, they are used to make secure and vital connections such as those required when using single rope technique,http://www.cave-crag.co.uk/721/Maillon-Rapide-10mm-Semi-Circular.html or for attaching ropes to anchor points. In climbing, they are used to construct leave-in-place abseil anchors. Maillons can also be used for fastening harnesses with a dual attach ...

Lead Climbing
Lead climbing (or leading) is a technique in rock climbing where the 'lead climber' Glossary of climbing terms#clip in, clips their rope to the climbing protection as they ascend a pitch (climbing), pitch of the climbing route, while their 'second' (or 'belayer') remains at the base of the route belaying the rope to protect the 'lead climber' in the event that they fall. The term is used to distinguish between the two roles, and the greater effort and increased risk, of the role of the 'lead climber'. Leading a climb is in contrast with top roping a climb, where even though there is still a 'second' belaying the rope, the 'lead climber' faces little or no risk in the event of a fall and does not need to clip into any protection as the rope is already Anchor (climbing), anchored to the top of the route (i.e. if they fall off, they just hang from the rope). Leading a climbing route is a Rock climbing#Description, core activity in rock climbing, and most first ascents and first fr ...

Quickdraw
QuickDraw was the 2D graphics library and associated application programming interface (API) which is a core part of classic Mac OS. It was initially written by Bill Atkinson and Andy Hertzfeld. QuickDraw still existed as part of the libraries of Mac OS X, but had been largely superseded by the more modern Quartz graphics system. In Mac OS X Tiger, QuickDraw has been officially deprecated. In Mac OS X Leopard applications using QuickDraw cannot make use of the added 64-bit support. In OS X Mountain Lion, QuickDraw header support was removed from the operating system. Applications using QuickDraw still ran under OS X Mountain Lion to macOS High Sierra; however, the current versions of Xcode and the macOS SDK do not contain the header files to compile such programs. Principles of QuickDraw QuickDraw was grounded in the Apple Lisa's LisaGraf of the early 1980s and was designed to fit well with the Pascal-based interfaces and development environments of the early Apple syste ...

Rappelling
Abseiling ( ; ), also known as rappelling ( ; ), is the controlled descent of a steep slope, such as a rock face, by moving down a rope. When abseiling, the person descending controls their own movement down a static or fixed rope, in contrast to lowering off, in which the rope attached to the person descending is paid out by their belayer. Description The technique is used by climbers, mountaineers, cavers, canyoners, search and rescue and rope access technicians to descend cliffs or slopes when they are too steep or dangerous to descend without protection. Many climbers use this technique to protect established anchors from damage. Rope access technicians also use this as a method to access difficult-to-reach areas from above for various industrial applications like maintenance, construction, inspection and welding. To descend safely, abseilers use a variety of techniques to increase the friction on the rope to the point where it can be controlled comfortably. The ...

Belay Device
A belay device is a mechanical piece of climbing equipment used to control a rope during belaying. It is designed to improve belay safety for the climber by allowing the belayer to manage their duties with minimal physical effort. With the right belay device, a small, weak climber can easily arrest the fall of a much heavier partner. Belay devices act as a friction brake, so that when a climber falls with any slack in the rope, the fall is brought to a stop. Typically, when the rope is held outward, away from the body, it moves relatively freely, so the belayer can take up or pay out slack. When the rope is brought backward, to the side of the body, the rope is forced into tight bends and rubs against the device and/or against itself, allowing the belayer to arrest the descent of a climber in the case of a fall. This rubbing slows the rope, but also generates heat. Some types of belay devices can arrest a fall without the belayer taking any action, while others require the belay ...

Munter Hitch
The Munter hitch, also known as the Italian hitch, mezzo barcaiolo is a simple adjustable knot, commonly used by climbers, cavers, and rescuers to control friction in a life-lining or belay system. It is often mistakenly identified as the crossing hitch, however in the cross hitch the line does not return along its original path. To climbers, this hitch is also known as HMS, the abbreviation for the German term , meaning ''half clove hitch belay''. This technique can be used with a special "pear-shaped" HMS locking carabiner, or any locking carabiner wide enough to take two turns of the rope. In the late 1950s, three Italian climbers, Mario Bisaccia, Franco Garda and Pietro Gilardoni developed a new belay technique called the "Mezzo Barcaiolo" (MB) meaning; "a half of the knot, which is used by the sailors to secure a boat to a bollard in a harbor." The "MB" came to be known as the Munter hitch after Werner Munter, a Swiss mountain guide popularized its use in mountaineeri ...
