Summary
Our project was to design a mechanism that mirrored the human motion of sharpening a knife with a whetstone. Using a whetstone to sharpen a knife is a very intuition-driven process of maintaining specific angles of the blade relative to the whetstone, and it follows a complex human path that is difficult to reproduce with mechanisms. This brings us to the challenge of the project, which is to create a linkage mechanism with one input driver that can mimic the motion of the sharpening. The model for the design was to create a linked oscillating four-bar and slider-crank system that moves both the whetstone and the knife to evenly sharpen the knife along its entire profile, from hilt to tip.
