1975年,英国登山队员斯柯脱和海斯登在攀登珠穆朗玛峰西南坡时,途中遇到暴风雪,不巧海斯登的氧气瓶输氧管道被水汽冰冻而堵塞。此时此地无氧可吸的后果是显而易见的。危急之中,斯柯脱掏出随身携带的小刀,捅破冰块,使同伴脱离了险境,最后他俩登上了地球的顶峰。这个故事说明,野外活动绝对离不开刀具。 In 1975, British climbers Skoda and Haisdon encountered snowstorms on their way to the southwestern slope of Mount Everest. Unfortunately, Heisden's oxygen cylinder oxygen line was clogged with water and ice. At this point the consequences of anaerobic respiration here is obvious. In a critical situation, Skoda pulled out his carry-on knife and pierced the ice to keep his companions out of the woods, before finally landing on the top of the earth. This story shows that the absolute freedom of movement can not do without activity.
