I've wet shaved forever. I used several cartridge razors until about 12 years ago when I switched to DE razors. I used a Merkur 23C until the last couple of years. I now have several others and switch between them often. I've had the Merkur 39C for a couple of months and recently bought a Parker Semi Slant. The Parker is my only razor that seems to leave my face a little irritated. I thought it was suppose to be milder than other slants. What do you think?
