So after a few VERY mild and smooth shaves with a RazoRock 37 Slant, I ordered a Merkur 39c. I loaded it with an identical Astra blade lathered up a bowl of Arko and proceeded to remove three days growth. The Merkur was NOT smooth at all. I perfectly centered the blade, and used the same angle as the other head but other than removing the growth, it was not a success in my opinion. Upon closer inspection, I noticed that the blade reveals appear close to identical between the two razors, but there’s a modest blade gap with the RazoRock. With the Merkur, the blade is pressed firmly against the base plate. Is the normal for this model or do I own a dud? I can quickly create some blade gap with a very slight loosening of the tail cap, but obviously that’s not how it’s designed to be used.
