I have been DE shaving regularly for about 5 years or so, after a lifetime of electric and cartridge shaving, with some limited fumblings with DE's about 40 years back when i started shaving.
My regular DE is a Merkur 20c with Astra SP blades, which works well for me. I have a few others i have acquired, but keep coming back to this combo. I do still keep and use a Gillette Fusion on occasion.
