Knurled surfaces in Hexagon
So i'm off on a crazy angel here and thought about replicating a jeweller's screwdriver similar to this one.
I started a quick test to see how it would look, boy is this stuff time consuming, no speed modelling here even though the rest is simply extrudes the knurls are a time killer.
To do this i started with a segmented cylinder, selected the middle section and tesselated the faces into diamonds. I then selected a series of diamond faces and extruded with taper.
