I love my Merkur 34HD and the red personnas. So much that i bought a hundred of the blades. I only shave 2-3 times a week, so these will last me forever!
Everyone swore that the feathers are the best blades, but damn do they tear my face up bad. Closer shave with the personnas than the feather blades too
Put it all in the primary, and let the BeerGods sort it out
