That old carabiner ...... where did you get it ?

这个旧钩子你从哪拿到的？

Second : the shape of the carabiner plays a role in how sharp the worn edge can be .

第二：钩环磨损边缘的锋利程度与它的形状有关。

This scenario could occur when any two pockets are connected to a single carabiner

当任意两个环连接在一把主锁上时，都有可能发生这种危险。

This wearing pattern can occur on any i-beam or wide-to-narrow carabiner design , and photos of the tapeworm carabiner confirm that it was at that stage .

这种磨损情况会发生在工字型锁或者由宽变窄的钩环上，tapeworm事故钩环的照片证实了这一点。

Accidents involving cut ropes are rare , but not unheard-of . Kolin powick , on his black diamond blog , reported hearing of a similar accident , this one in a prague climbing gym in 2008 , when a rope was cut by a sharp carabiner , also located at the first bolt .

绳子被割断的现象还是很罕见的，不过kolinpowick在他blackdiamond日志里曾记录过2008年在布拉格岩馆里发生的类似事故，那次绳子也是被第一把快挂割断。
