早在一百多万年以前，人类的祖先就已经开始使用工具了，他们通过各种石器工具放大了牙齿、手臂和手指的能力，就比如钻木取火，燧石取火，用石斧砍柴，用石刀切割猎物。 但是当时的器物，都只剩下不会随时间消逝的石头部分，也许看到一个很尖锐的石块，却不知道它应该是如何使用的。 来自以色列特拉维夫的设计师Ami Drach和Dov Ganchrow设计了一系列石器工具，以一种现代的方式再现了人类祖先所使用的工具。 设计师们通过3D扫描、3D打印、快速建模、镀银等技术复制出原始工具，并给这些工具设计了手柄，最后得到了如下这些石器工具。 这不是历史性真实的还原，更多的是一种艺术的表达。在石器与手柄贴合的部分，仔细看使用了扫描技术，逆向建模设计出一个可以完全包裹的结构，再进行打印制造。 Keyword: 优化型外贸独立站
