Not Just Another Screwdriver 









Third-Year University Project

Duration: 15 Weeks




Brief


Most hand tools today still follow ergonomics shaped by mid-century military data, built around an imaginary average. They dictate how to grip, how to use, and what not to do. But the screwdriver wasn’t made to be obedient. It was made to open things, break things, fix things.

How might we design a screwdriver that behaves like a small system, not a finished object open to repair, variation, and misuse existing somewhere between a tool, a toy, and a critique of what design calls progress?

This project reimagines the screwdriver as something that doesn’t just perform a task but changes through it. A tool that stays alive through use.

Description

This isn’t just a new tool. It’s a critique. The screwdriver breaks apart into multiple components, each with its own connector and logic. The system is modular, repairable, and open to misuse. You can change the rod, extend the spine, swap out the core, or print a grip that works for your hand. Nothing is fixed. Everything can shift.

The grips are fully open source. You can use the ones I made, generate your own from hand data, download someone else’s, or just model it yourself. The idea isn’t to find the perfect grip. It’s to move away from pretending one exists.

Parts can be printed locally or ordered. The metal components can be returned and fed back into the system through a buyback scheme. Nothing is wasted unless it’s meant to be. The whole thing is built around use, wear, and eventual repair.

It isn’t here to stay clean. It’s here to stay alive.

A step to a less boring future.

Custom Grip 

Download your own custom grips.

All you need to do is take a photo of your hand on any A4 sheet of paper. Upload it to the website, follow the steps, select all four corners in order, and run the measurement tool. You’ll then get access to custom CAD files for grips sized specifically to your hand.
