Not Just Another Screwdriver

Third-Year University Project

Duration: 15 Weeks




Brief
Over two billion hand tools are made every year,
yet much of the ergonomic thinking behind them still comes from mid-century Western military data. Less than 15% of global anthropometric data represents anyone other than white men aged 20–30.

So the “average” hand we design for isn't really average. It is a statistical shortcut that has been repeated until it feels like common sense. 
The result is a rigid idea of how a tool should be held, used and even what it should look like. The user adapts to the tool, rather than the other way around.

The brief was to give that authority back.
How might a screwdriver become an open system that can be adjusted, repaired and reworked by its user?
The aim was never to find the perfect handle. It was to challenge the idea that one should exist.

Description

An open-source, modular screwdriver system built around the idea that there is no universal hand, and no single correct way to use a tool.

Instead of being a finished object, the screwdriver is designed to change with the person using it. Grips can be downloaded, printed, customised and replaced, allowing the user to shape the tool around their own hand, habits and needs.

The system gives the user the authority and autonomy to change the tool, rather than asking them to adapt to a fixed standard.

It is not one perfect screwdriver. It is a screwdriver that can become yours.
