“Merkur and Feather blades here.”
Feather blades are very thin and VERY sharp, and one has to be VERY careful using them. However, once one becomes proficient at it, they can give amazing shaves.
I buy Wilkson Sword in bulk, so they are pretty inexpensive.
My biggest expense is the shaving soap, but I go with Van der Hagen, which is the most affordable, and works just fine for me.
I’ve only cut myself once with the feather, early on and I didn’t know until I saw the blood (not bad though).
