I promise, I'll try to take it easy with the superlatives. But I just shaved with a Joseph Elliot "Best Silver Steel" 6/8 wedge that Tom at Jendeindustries honed for me. It was finished on Ken's Cubic Boron Nitride spray on balsa @ 0.125 microns. And it is the sharpest razor I have ever shaved with It's noticeably sharper then razors I've tried coming of .25 diamond & the Shapton 30K Pro. Tom told me that from the test shaves he did that it was I "can expect a new level of BBS" And that sure is true! And maybe this razor can stand up to the title? I really think it's hard to get a blade any sharper then this & still be able to shave with it. When I first unpacked it, I was like a kid at Christmas, I just had to play with it before shaving. HHT with my wife's (I'm bald myself ) "normal" brunette hair was a good first measure. It fell silent from touching the edge, holding the hair well over 2 inches from the blade. I upped the ante & went for my 2-year old's flimsy blond hair. Same results... I even came up with a new test. "The falling flimsy blond hair test" It consists of dropping 1 flimsy blond hair from 2 inches above the edge. 2 out of 3 times the razor severed the hair cleanly.. Now I was getting a little tense. Standing in the shower I could actually feel my pulse slightly rise. "Could an edge this sharp really be comfortable?" "Would I come to work looking like Jason Voorhees?" Well you know, no guts no glory & all that & I threw myself in the deep end... Lathered up some Palmolive & gave the blade some laps on the Buffalo leather. OK...here we go.. After a few strokes on the right side of my face I had a silly grin on. "This is ridiculously sharp!" 2 days worth of stubble just disappeared. And the cheek was left smooth, same thing with the neck. I didn't even have to go over the same spot more then once. But it sure needed a new level of concentration. I'm always focused when I shave with a straight, but still I have enough experience that I can somewhat relax & just let the hands do what feels best & sort of go with it. Sort of autopilot/zen if you like. Not possible with this edge. As soon as I got in that state it dug into my skin. Nothing serious, some Proraso cut gel stopped the little bleeding immediately. With any other edge this had just been a feeling of "Oops, a little to steep, better start over" After a full pass I was really smooth, I could easily have gone to work, wearing a suit & a tie & thought nothing of it. But why stop here?! Lathered up again for a XTG. No worries at all. Except that I could feel the edge several times trying to dig in. Around the jawline I actually had to go with less then no pressure. I sort of supported the weight of the razor just to keep it from biting. But once I figured that out, it went without any problems. Time for ATG. I wasn't really needed actually. A little clean-up around the muzzle would have been sufficient. But I went at it & the 150 year old Mr Elliot just didn't care. He cut the remaining traces of whiskers with the same ease his old makers had after-noon tea on the front porch.. I was really surprised how good my face felt after wards, absolutely smooth but also quite comfortable. No rawness or irritation. Slapped on some Spanish Floïd & it did sting a little more then usual, but nothing severe at all. Jason's balm atop & now, an hour & a half or so later, I feel great! Very, very smooth & not irritated or red at all. For some comparison the other two edges I've tried that comes somewhat close to sharpness is .25 diamond that leaves me with a harsh feeling & irritation & the Shapton 30K pro edge that is the closest in sharpness & also shaves very, very close. But it has a different feel, a slightly "gripping" feel to the edge. On the other hand, the 30K edge is somewhat more forgiving. Maybe simply because it isn't as sharp as this one. The .125 edge was much more smooth then I anticipated. It somehow reminded me of a well honed Escher/Thuri edge, but so much sharper! Like I wrote earlier I don't think I could shave with anything sharper then this. Maybe someone with tougher skin can handle sharper (if you can get it!) And I don't think this edge is for everyday use, not for me. But man this sure was a great ride! And it is a great razor to have in the rotation! I'll definitely use it some more. Edge longevity will be interesting after a few shaves. And now I just can let go of the thought what 0.125 CBN would do to a full hollow MK series Heljestrand For full transparency I consider Tom a good friend & I've had many great conversations with him thru PM's. And he honed this razor for me for free. But please believe me wen I say that the above review is based solely on my own experiences without any hidden agendas.
