As an avid home cook and baker, I enjoy my time in the kitchen - most of the time, anyway. One exception is the numerous cut and burn injuries I've sustained throughout my cooking life. I found that many people have the same problem, so I wanted to try my hand at creating a product that could help reduce the number of cooking injuries for home cooks. What I really wanted to do was make something that could improve people's cooking safety without them even realizing it, and certainly without them having to learn a new skill, pay extra attention, or change their habits (knowing that most users wouldn't go through the trouble).
After researching statistics about the biggest causes of injury in the kitchen, I decided to focus my design on preventing accidental cuts from kitchen knives. By researching online cooking websites and forums, talking to professional chefs, and surveying home cooks, I learned more about the causes of blade-related cooking injuries. Two often recommended approaches to avoiding accidental cuts were using a special grip called pinch grip, offering enhanced control, and maintaining the blade by honing and sharpening regularly. However, most home users do not use these techniques due to a lack of formal training.
I decided to design a product that would make using pinch grip intuitive and natural, even without formal training. In addition, I wanted to come up with a way to make maintaining the blade effortless.
I took clay molds of various users using pinch grip. These molds gave me an idea of what an ergonomic, pinch-grip inducing knife handle would look like. I used the resulting form as the basis of my design.
Using the composite image from the clay impressions as a starting point, I created foam models to conduct user testing. Using feedback from the user testing, I made modifications and arrived at the final form.
