First - Based on just the visual appearance of these things - I'm not sold on why anyone wants to use a Kamisori. They look like a cross between a meat cleaver and a cheese knife; when you really look at it close up in your hand its just a menacing kind of blade.
Reading the comments here/there I thought maybe I was missing out on something so I decided to try one.
I got a 45mm Asuma, Yasuki steel, nothing really special I guess but it's pretty nice.
First shave went ok, but something was off so I rehoned it.
Second shave was ok but something was still off so I rehoned it again.
Third shave was better but not what I wanted so - yes - I rehoned it.
Same deal. WTF?
Ok - For the 4th spin - I decided to just go on instinct and feel. I used a new Ozuku (not the big one, another new one) so I had that variable to work with but I was semi-dialed into it already. Anyway - I used info from the aforementioned (verifiable, knowledgeable, and proven) souce and had at it.
I managed to get the bevel done right this time - Yae Botan got me home and Koma iced the cake. Sprinkles provided by a chunk of Mizu Ozuku that I consider to be a miracle stone.
I haven't cut myself in a long time. Nicks - yeah, slices - no. Till today. The cut happened because I wasn't respecting the edge or the spike and I got careless. I never felt it, I just watched it happen - it bled but it stopped pretty quickly.
I'm not blaming anything but my own carelessness here - but honestly, the edge is so freaking bizzarely sharp and smooth so I can see how my technique has to improve or I'm going to need a personal blood donor. FWIW - This blade is sharp like I've not experienced with a razor before.
So - what I think is that this little cleaver of a razor has some promise as a shaving implement, but I'm still not sold on it as being one that I'd really enjoy in the long term.
The hard/soft steel construction is interesting, the short hard slab of cutting edge (obviously) has merit. I do like not having to deal with working around scales at times too. But even so - it just seems weird somehow. And I don't know what to do with it when I want to put it down. Folding a traditional straight up allows me to just put it wherever I want to. The Kami needs a secure stand or something. Not sure what to do about that, but I can't have an open blade hanging around in the bathroom, or anywhere else, like that.
At any rate - I'm kind of happy I nailed the edge, and got a laser-razor shave from it. The cut proofed the edge so even that's ok.
I didn't put much wear on it during the honing sessions, so I can keep playing around with progressions and stuff a bit if I decide to keep going with it.
But still - at the sake of sounding redundant - shaving with this Kamisori just seems a bit weird.
