Congrats on the Merkur. Realize you can't have just one razor, or six or twelve for that matter. So, make it a goal to get a fine old open comb Gillette. You owe it to yourself.
I used my new to me 1905 double ring old type, open comb, for the first time this weekend. It gave me a fantastic shave. The best DE shave I have had, I think. I highly recommend one for your next purchase.
