I'm new to head shaving, but not wet shaving, so I figured I'd try a shave with only a DE. I went for the most aggressive choice possible, hoping that I'd get a closer shave than the previous two I'd done, one with a Mach 3, and the other with a standard Merkur (I don't know the model number, but it's not the HD; it's a lot lighter), but only on the sides of my head (more flat surface area, less risk of getting cut) - I went with a Merkur Slant Bar and a fresh Feather blade. I used a badger/boar brush and TOBS Avocado shave cream.
The shave was cut-free, although the sides of the back of my neck are a bit irritated (the Slant has never given me a completely irritation-free shave on my face, though, so I'm not surprised). Overall, it was closer than the previous two head shaves, but I also owe that to a shorter time period between shaves.
After one pass with the grain I was confident that I'd be able to do against the grain, but I'm having the same issue as with the Mach 3 and the other Merkur - the blade skips when I go against the grain. As a result, I'm going across the grain on the second pass, which gets closer, but doesn't get me to the elusive BBS. As I sit here, about 2.5 hours later, my head feels very stubbly if I rub it against the grain.
I'd like to stick with the DE because I still have a decent supply of Feathers, and I don't shave most of my face since I have a beard. I'm quite surprised that this combination, of any razor and blade, still resisted going against the grain. Is this goal simply unrealistic for a new head shaver?
