Since the early 1970’s, the Porsche Design Studio has produced a wide assortment of contemporary accessories, tools, and home goods (the group was founded by F.A. Porsche, and is a part of Porsche SE). Some were quite groundbreaking for their time and continue to influence designers today.
After all these years they’re still going strong, and my favorite pieces recently created by them that I use regularly are a santoku chef’s knife and a mechanical pencil (both are very comfortable to use for long periods of time). The lighters are quite cool as well.
Here are a few ads showing some of their creations from the 80’s and early 90’s. The older sunglasses in particular have a bit of a cult following and can fetch high prices through vintage dealers and ebay.
