Introduction: A Hammer for Jacob
Jacob is An 82-year old carpenter who lost three fingers on his right hand.
The hammer we've designed will provide more friction and will strengthen his grip-
this way he'll be able to work safely.
Step 1: The Hammer
We started by trying to pinpoint the exact difficulties he experiences
when working with the hammer.
His main problems:
Not enough friction around the handle
He mostly uses his thumb and pinky when holding objects, which creates
an elliptic shape between his fingers instead of a round one.
The hammer has 2 holding areas:
one for a stronger lift and hit; and one for more delicate work.
Step 2: Instructions
Use the stl. files to create the handle on a CNC machine.
attach hammer to handle with metal wedge.
