The earlier prop designs, such as the K3 model, took many years to create and produce. With the help of Rhino and modern production methods, the later designs, such as the K4 and K2, were built in under one year.
Rowan Blundell notes, "All of the propellers are multiple, intersecting helix surfaces, so really was a challenge initially to obtain nice joins!"
The props are first 3D-printed in ABS. Later they are cast in stainless.
