I've found matching razor design (i.e., hollow/half-hollow/wedge) to skin type is paramount
. I have an Über coarse beard & particularly sensitive skin... I'm a full wedge kinda guy.. hollows get closer, but burn like a bee sting on me.
I also suggest practicing ad nauseum on a blunted tester. My first straight was from WhippedDog, and as it was absolute garbage frowning from ear to ear, instead of tossing it where it belonged into the circle file - I blunted it & used it as a practice tool.
You must stick with it to perfect your craft. I'm guessing I'm two years in, and I can only shave on days off...
when they come. No way can I blast through a perfect shave closer than any straight shave I've had yet w/o even a hint of burn in 2 minutes like I can with a disposable racing to work. It's a total luxury activity to me.
