Thanks Craig. I know nothing about blade patterns, but found this - Raindrop/Bird's Eye/Pool and Eye: A stacked billet that has had shallow depressions drilled or ground into it, and is then flattened.
There is an example at the bottom here

Also found this neat combination blade pattern by Mick Maxen (UK)



A 4 Iron 'Star' barrel pattern



'Horse-shoe' refinished by Paul Stevens
