Is there any quantifiable difference between Astra Green and Astra Blue? I have ordered the blues, but not the greens.
+1Purportedly, the Platinums are 'smoother', the 'Blues' a bit sharper. Each has their following and both blades are quite excellent and highly regarded.

in R41, the difference is felt. In milder merkur HD, I cannot distinguish the two.
