It is necessary to develop a layout-construct of a badge-opener for a sommelier. Examples are attached. The size should be 100/70 or 90/60 as appropriate, so it is not too bulky.
The main idea is for the badge to perform three functions:
- Bottle opener of the "beer" type
- Mini-knife, like a sommelier's
- Corkscrew
No other tools are needed.
Important point — attachment: the badge should stay on the waiter's shirt using a magnet, meaning a magnet on both sides of the shirt, and the badge itself, made of iron, easily attaches to the magnets.
When the waiter needs to open something, he simply removes the badge and uses the required function.
The appearance should be concise, modern, without unnecessary elements, so that the badge looks organic on the uniform.
