Ehil
Multi Functional Döner Knife
1st Prize Winner / Immib 2017
http://immib.org.tr/en
Döner, very well known and famous all around the world, almost the most consumed traditional food in Turkey, is mostly preferred in a sandwich like a fast food in daily routine. The aim of this project is to focus on the workflow to prepare a full sandwich and to design a product to make it simpler and faster for the chef and healthier for public which means to design a really
skilled knife.
Existing Workflow and Tools
One Chef + Several Tools = One Döner Sandwich
Chef normally needs several tools like shovel, tongs, scale, spoon, knife, sharpener...
to prepare a full sandwich.
These tools, placed carelessly somewhere on the worktop, creates both mess and unhygienic circumstance which threatens the public health. Besides, that workflow to prepare a sandwich with these several tools is not efficient and slows down the process. There can easily be seen a long queue in front of that fast food buffets waiting for a sandwich of döner.

Very thin layers of döner shows the quality of it and the place. Slicing very thin layers needs master skills that's why all restaurants work with the same chef everytime. It is possible to slice thin layers of döner with the
specially designed blade of Ehil inspired by Peelers.
This makes Ehil innovative.
