The irregularity of hand-split stones was a design advantage.
Irregular stones were not simply a flaw
Prague City Tourism explains that older cobbles were split by hand, which left them with irregular shapes rather than machine-like uniformity.
That irregularity created design freedom
The same source connects those hand-split shapes with the ability to form both straight and curved pavement patterns. Variation in the individual stones helped the surface adapt to different geometries.
Read the pattern before judging the stone
A useful way to look at Prague paving is therefore to stop treating irregularity as evidence of poor precision. In this older craft logic, the uneven shape of a single stone could contribute to the flexibility of the pattern as a whole.
