Oh, what a misguided little shit I was when I first posted in this thread.
Double-edged safety razor master race reporting in. I started with a Merkur I purchased in 2013, then inherited my great-grandfather's Gillette from the 60's. Purchased a 50's era Gillette Red Tip, which is now my every (other) day shaver. I use only feather blades, as they work best for my skin. Razorock soap and alum block + Clubman after shave.
