Raw cut geometry straight off the band saw, with laser-cut mock blade and the illustrator outlines used as a guide.
First (of three) generations of model used both for empathy testing and presentation to the user group.
Developments inspired by both the empathy testing and the insights of the users from the second workshop.

Kitchen Utensils for older users
> Fourth university project of third year
> Brief: To re-design certain kitchen utensils, taking into account the physical and cognitive needs of older users.
> Utensils given to re-design: Bread Knife and Paring Knife, two knifes used for very different purposes.
> Both knives are designed to support older users, by allowing more comfortable and ergonomically sound postures during use.
> A heavy use of foam modelling and empathic research tools aided me in the creation of suitable form.
> Modelled in PTC Creo and rendered in Autodesk 3ds Max.
