Kinda badass. Designer Mia Schmallenbach has designed a set of knives based on the Fibonacci sequence.
The Fibonacci sequence, you’ll no doubt remember from school, starts with 0, 1 and continues by adding the previous two numbers together: 0, 1, 1, 2, 3, 5, 8 and so on. It can then be used to make shapes. Plotting squares whose sides are the length of successive Fibonacci numbers and then drawing an arc through their opposite corners will give the Golden Spiral, a shaped found in nature: the nautilus shell, for example. By making this shape, along with others suggested by the sequence, Schmallenbach came up with the design
