The handle of climbing stick is usually made of EVA, rubber, cork, plastic and other materials. Each material has the following characteristics: EVA: comfortable grip, full and elastic, not affected by the season, and the material has the function of absorbing sweat; Rubber: full grip, hard and easy to crack in winter, no sweat absorption function, easy to slip in summer; Cork: full grip, not affected by the season, with sweat absorption function, easy to wear and desquamate; Plastic: poor grip, easy to crack in winter, easy to slip in summer, but low cost, cheap and convenient.
The wrist strap is the most important part to consider when purchasing a mountaineering stick. Since the strength of the mountaineering stick and the user is mainly transmitted through the wrist strap, you should consider whether the high-quality wrist strap has the following characteristics when selecting it: the middle part of the wrist strap is wide, and the two sides are narrow, which can prevent strangulation; The wrist strap adjusting clasp is arranged at the connection with the climbing stick, and does not contact with the hand to prevent the hand from being hurt; The inner side of the wrist strap is made of suede anti friction material, which effectively protects the skin contacted by the wrist strap.
Strut
The supporting rod is usually made of aluminum alloy, carbon drill rod, titanium alloy, wood, steel and other materials, among which aluminum alloy and carbon fiber are the most widely used. Several materials have the following characteristics: aluminum alloy: solid and durable, low price, heavier weight than carbon fiber and titanium alloy, and easy to corrosion; Carbon fiber: light weight, good elasticity and toughness, high strength ratio, corrosion resistance and high price; Titanium alloy: light weight, good material elasticity and strength, corrosion resistance, high price.
The locking system is the core safety component of a climbing stick, and 90% of climbing stick problems are caused by locking system failures. Low price climbing sticks generally use common plastic parts that are easy to change, while high-end climbing sticks use high hard engineering plastics (crystal plastics) and are precisely cut. Such as the industry recognized advanced locking system, Flicklock joint locking system independently developed by Black Diamond/Black Diamond, Robinson patented SLS second generation locking system, Wildview/Dewei's 3LS safety locking system, etc.
At the same time, the aluminum alloy climbing stick will be equipped with a shock absorption system together with the locking system. As a spring component, the shock absorption system can effectively cushion the impact force. When going downhill, it can reduce the pressure on the knee. However, because the spring will absorb the thrust when going uphill, it will consume additional energy when walking for a long time. In addition, the spring components with poor materials are prone to rust, fracture, slip, etc., which may cause the locking system to buckle or fail. The climbing stick made of carbon fiber and titanium alloy has good elasticity and toughness, so it can achieve a balanced shock absorption effect without setting a shock absorption system.
Mudjack
The mud support can prevent the climbing stick from falling into the mud. However, there are many thorns and shrubs in the mountain crossing environment, and the mud support will hinder the convenience of movement. Therefore, it should be noted that the mud support can be quickly disassembled and assembled to avoid trouble.
The tip is made of rubber, iron, carbon tungsten steel, etc. Carbon tungsten steel is the hardest, the most expensive, and the rubber head is the cheapest, but it can not cope with rugged outdoor terrain, and its wear resistance is not as good as carbon tungsten steel head. The common patterns at the tip of the staff are net pattern, diamond pattern and grid pattern, among which the diamond pattern has the best anti-skid and penetrability.
