用粪便做的刀?

　　Many scholars are familiar with the strange story of an Inuit man who, upon being stranded during a storm, fashioned a knife from his own frozen poop and used it to butcher a dog. Although the tale is famous among anthropologists, none have attempted to craft their own blade from frozen fecal matter — until this year, that is, when a team of researchers took a hack at crafting their own poop knives. The lead study author, Metin Eren, adopted an "Arctic diet" for eight days to supply the needed raw materials, which the team then froze and shaped into blades with metal files. But when the team attempted to carve up a pig hide with their new knives, the blades only left brown streaks along the meat.

　　许多学者都熟知一个关于因纽特人的奇怪故事。故事中的一名因纽特人在暴风雪中被困，他用自己被冻成冰的粪便做了一把刀，然后用它宰杀了一条狗。虽然这个故事在人类学家当中流传甚广，但从来没有人尝试过用冷冻粪便来制作刀具——直到今年，一个研究团队尝试了打造自己的粪便刀。研究报告的第一作者梅廷·埃伦经过了为期8天的“北极饮食”来提供所需的“原材料”，然后研究团队将这些“原材料”冷冻起来，再用金属锉刀把它制作成刀的形状。但是，当这支团队尝试用他们新做的刀来切一块猪皮时，却只在肉上留下了棕色的印子。
