The venerable R41. My favorite razor bar none. I have a Mergress XL, Gillette Slim, Merkur 38c and my beloved R41. Yeah, I nicked a little trying to get used to it, a little blood, but no big deal. I read where a heavier handle improves the performance of the R41, so I ordered a Tradere handle. The heavier handle drew more blood. My R41 with the rose gold handle has the perfect weight for an aggressive razor, and with rose gold, it's sure nice looking. From my experience, Personna Med Prep blades work well with the R41, but really any blade in an R41 does the trick. My first R41 came with a slightly damaged head, so since I ordered directly from Muhle, they sent me a replacement. So I have two R41's. The R41 does in two passes what other razors do in 3-4 passes.
