Inspired by the simplicity and efficacy of Stone Age tools, this fresh herb chopper was created as a more ergonomic alternative to your classic knife.
The hand applies force in a position that doesn’t require grasping or excessive pressure to be applied when crushing (see images above). Compared to the motions performed on a knife, this tool is an improvement in comfort and efficiency for all users, especially individuals with physical challenges such as rheumatoid arthritis or carpal tunnel syndrome.
The project brief stated one constraint: the tool has to have one hole. Prototyping brought about the realization that this hole could be incorporated in the blade to serve a second purpose: crushing.
For this secondary purpose, the tool is turned around and the fingers go through the hole in the blade. Here, pressure is applied in a downward motion to crush certain herbs such as mint or even garlic.
The grey prototype, made using plasticine and a metal ring, is the works-like (functional) model, used to showcase the proposed functionality of the final product. A looks-like (visual) prototype was also created out of high-density foam, presenting the tool in its final visual form.
Sketches and early prototypes were created to explore form and functionality.
