I've certainly noticed a difference in the coarsness of crossgrain on different manf. blades.
Eickhorn produce a high quality blade that looks 'smoother' than some others, that may be down to quality control being at a higher level than other manf. Whatever the reason for it I wager that when it was being done the polishers would have never thought it would be a talking point 70 years hence.
