Slate was a prominent tool material in the Scandinavian Stone Age. However, details of tool function have relied on morphology and have added little to our understanding of their role in hunting and processing. Here, we demonstrate that it is possible to identify both the use-wear traces and residues from slate knives from northern Norway. By applying a multi-disciplinary approach incorporating experimentation, use-wear and organic residue analyses, we identified residues, including seal hair, and use-traces which indicate the tools were used to process fresh marine mammals.

超越其他：对挪威沿海地区觅食环境中的两把石板刀进行的多学科研究

板岩是斯堪的纳维亚石器时代的重要工具材料。然而，工具功能的细节依赖于形态学，并没有增加我们对它们在狩猎和加工中的作用的理解。在这里，我们证明可以识别挪威北部石板刀的使用磨损痕迹和残留物。通过应用结合实验、使用磨损和有机残留物分析的多学科方法，我们确定了残留物，包括海豹毛发和表明这些工具曾用于加工新鲜海洋哺乳动物的使用痕迹。
