Ergonomic utility knife
Spring 2021 - Year 2
Class focus: Ergonomics.
Prompt: Design an ergonomic utility knife in a two week timeframe.
Getting in the shoes of the user
I used an existing utility knife to test how I was able to carry out task under various impediments that users may encounter.
Taped fingers: Simulating hand disabilities.
Using the knife with thick gloves.
Form exploration
My focus was on creating forms that would help keep the wrist in a neutral position.
Testing comfort
Having multiple ways to hold the knife allows the user to discover how they can work best with the tool.
Neutral wrist position = More comfort
Slight refinements
Greater stability
Thinner main body feels better in the hand.
More finger space
The slider no longer interferes with the index finger when doing high precision cuts.
Ambidextrous
Symmetric design with a thumb grip area on both sides of the knife allows for right and left handed people to use the knife in the same exact way.
