Abalakov Thread
250px, Abseiling at an Abalakov thread The Abalakov thread, also known as a V-thread, A-thread, or 0-thread (zero thread), is an ice protection technique named after its innovator, Soviet climber Vitaly Abalakov. The Abalakov thread is a common method of protecting oneself while ice climbing because it is easy to create, does not require the sacrifice of expensive gear, and can be very safe when used properly. An Abalakov thread is often used in multi-pitch ice climbing routes. Because of its safety and convenience, the Abalakov thread is considered one of the most significant innovations in ice climbing. It significantly expanded the scope of possible routes and abseiling safety. Description An Abalakov thread can be constructed using an ice screw, of appropriate strength cord or webbing, and hook-like Abalakov threading device. Two holes are drilled in the ice, which interconnect at the ends to form a v-like channel in the ice. The cord or webbing is then threaded throug ...

Abseiling
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 the rope, in contrast to Belaying, lowering off in which the rope attached to the person descending is paid out by their belayer. This technique is used by Climbing, climbers, mountaineers, Caving, cavers, Canyoning, canyoners, search and rescue and rope access technicians to descend cliffs or slopes when they are too steep and/or dangerous to descend without protection. Many climbers use this technique to protect established Anchor (climbing), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canyoning
Canyoning (canyoneering in the United States, kloofing in South Africa) is a type of mountaineering that involves travelling in canyons using a variety of techniques that may include other outdoor activities such as walking, scrambling, climbing, jumping, abseiling (rappelling), and swimming. Although non-technical descents such as hiking down a canyon (''canyon hiking'') are often referred to as ''canyoneering'', the terms ''canyoning'' and ''canyoneering'' are more often associated with technical descents — those that require abseils (rappels) and ropework, technical climbing or down-climbing, technical jumps, and/or technical swims. Canyoning is frequently done in remote and rugged settings and often requires navigational, route-finding, and other wilderness travel skills. Canyons that are ideal for canyoning are often cut into the bedrock stone, forming narrow gorges with numerous drops, beautifully sculpted walls, and sometimes spectacular waterfalls. Most canyo ...

Fisherman's Knot
The fisherman's knot is a bend (knot), bend (a knot for joining two lines) with a symmetrical structure consisting of two overhand knots, each tied around the standing part of the other. Other names for the fisherman's knot include: angler's knot, English knot, halibut knot, waterman's knot, and true lovers' knot. Though the fisherman's knot is associated with fishing, it can slip when tied in nylon monofilament and other slippery lines; however, if more holding strength is required, the overhand knots can be made with more turns, as in the double fisherman's knot, and so on. It is compact, jamming when tightened and the working ends can be cropped very close to the knot. It can also be easily tied with cold, wet hands. Though these properties are well suited to fishing, there are other knots that may provide superior performance, such as the blood knot. In knitting, the knot is used to join two strands of yarn. In this context, it is commonly known as "the magic knot". Image:S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
