Balding Beards' The 6 Best Safety Razors That Provide a Super Close Shave
All fine razors and I hope to try that Merkur out one day (I've got their earlier adjustable one) but an essential piece of advice about trying any new safety razor is, try a variety of blades. Don't assume the super sharp Feather blade is "best". It all depends on the razor and your own skin. Try a Feather blade (carefully) and try Astra SPs and a few others.
