A knife is one of the simplest tools we use every day, but what makes it your go-to knife? It's all about how it feels in your hand—the comfort, balance, and ease of use.

When I started designing my knife, I didn't know much about knives at all. But as I got deeper into the process, I learned a lot from watching visually impaired people use knives. They rely heavily on their sense of touch, which made me think about how I could bring that same tactile focus into the design.

That’s when I decided to create a knife that’s guided by feel. Every part of the design is meant to enhance that sensation in your hand, making the knife feel like a natural extension of you. The best part? You don’t need to see it to use it. The design allows both sighted and visually impaired users to have the same experience, levelling the experiencing field.

For me, this project is about more than just a knife. It’s about creating a more inclusive world through design, making sure that everyone, no matter their abilities, can have a great experience.
