Well I've been working on and off with my Nakayama Karasu to find a way to get a stable edge and today I was giving it a try when I got my first real owie. It was a simple lower lip WTG pass. I shivered and right where my razor would have stopped against the skin if it had been finished on any other stone, it swept right through and removed a chunk of my chin the diameter of a pencil eraser and about 3mm deep. I held the styptic on there for a good 30 seconds with a couple rewettings and was rewarded with a nice clean look at a hole in my chin. Very interesting. Did you know that there are regular little white specks (follicles?) on the very lowest layers of skin. I then finished my shave, put some antibiotic grease on the wound (to protect it from the agony I'm sure aftershave would have inflicted) and hit my face with some Pinaud Clubman. I pressed a bandaid on and then blood started up and soaked the gauze in a matter of seconds. Ouch. It's all the Nakayama's fault.
On the other hand, very nice smooth shave aside from the missing chunk of my chin and all. The stone is pretty interesting. Coming off the stone it cuts arm hair like a 3-4k finish. If I wipe the blade after honing, it wont even cut arm hair, so I go straight to the cloth strop with a wet blade. I strop it about 1/2 as much on cloth and about 2x as much on leather as I strop after my other stones. I'm rewarded with very clean silent falls. The edge seemed to hold up for this entire shave and was comparable to my Thuri's (Can't say if it's better or not yet). I'll have to see how many shaves it holds up for.
