Figure 1
Lab-µCT of clubs (a), (c), (e) 1 and (b), (d), (f) 2, with (a), (b) 3D renderings; (c), (d) a virtual slice through the clubs; and (e), (f) cut-out 3D renderings of the lower front half of the clubs shown from the back of the clubs. For visibility, the orientation of the cut-out 3D renderings (e) and (f) differs from those of the full club 3D renderings (a) and (b). Scale bars in (c) and (d) are 1 mm. The inset between (c) and (d) shows a sketch of the different regions in the club with the impact region in orange, the periodic region in green, and the striated and side periodic regions in blue; this was inspired by the sketch by Weaver et al. (2012

). The colour gradient bar illustrates the material density.
