I think I had posted earlier that I was a little "meh" with the Merkur Blades. I am going to update that thought. These things actually just suck. I loaded them in all my razors, Red Tip, Super Adjustable, Merkur HD, just to get an across the board comparison, and I think they are just grabby little suckers. Lots of drag. I am now wondering if that is why my First Tabac Shave was lackluster. I have also used the CVS brand blades, I think they are personna, not sure, and Derby blades. The Derby are my favorites so far. I have on the way, some Sharks and wilkinsons from melyus, and some feathers are on the way as well. More to try.
