Good Luck!!

    I also just received my Naniwa 12k today and man am i glad i bought it.

    Had that same problem of it sucking to my Dmt all the time so i was always moving it to the side with water to remove it.

    It took about 5 minutes to lap it and then i took one of my restored razors that i thought was giving me a pretty good shave as i had finished it with a chinese 12k.

    Now i don't no if it is psychological after seeing how everyone praises this stone as a great finisher but i got such an unbelievable shave, that it freaked me out.

    As soon as i lapped it i did 50 strokes(maybe a lot as i do a lot more than that on my Chinese12k.)

    Took a shower and proceeded with the shave.

    I did 3 passes and no AGAINST THE GRAIN and got a BBS shave everywhere except a couple of spots under my neck.

    I am always trying to improve my shave and this did it for me.

    Now i have to finish off my other razors and see if this was just luck or this Nani 12k is that awesome as everyone says.

    Thanks for the great info guys.

    I just got mine today too. My first hone woo
    Lapped it with 320 grit mastercraft wet dry sandpaper on a big thick glass plate/tabletop. Left it kind of coarse but I just rubbed it smooth with my dark blue escher slurry stone.

    The nani is a great stone, splash and go, but it will need to be lapped almost for every razor. It gets glazed and when lapping it you will notice hign and low spots on it.

    I use a DMT325 and never had any problems, I lap under running water, helps the sticking but does not eliminate it.

    Guys I'm new to straight razor shaving and bought a Norton4000/8000 which I'm getting on great with. All this praise for the nani 12k is it worth me buying one? or should I just for the time being go with the Norton?

    In my little experience now with straight shaving i would say master the Norton 4/8 k but in the meantime keep your eyes open for a good deal on a Nani 12k as it is just an amazing finisher as everyone recommended to me also.

    I have found after you shave great with your setup the Nani 12k will just bring you to another great level.

    For me it was almost night and day after i finished on this stone.

    It just took me a little while to get it as it was a little pricy for me.

    If i had known it was that great i would have bought it sooner but it gave me time to learn on my Norton 4/8k.

    Hope this helps.

    I just literally started honing for the first time, so take this FWIW, but it's consistent with another thread here on lapping Naniwa stones http://straightrazorpalace.com/hones...-not-flat.html. I took out a new 12k today and was going to lap with a new Naniwa lapping stone. But having read the thread I decided to check. Good thing cause the lapping plate was out way more than the 12k stone.
    I do machine work and have a precision granite inspection table, so I put the lapping plate on with wet/dry paper and saw the high spots. I didn't have coarse enough paper to bring it down in a timely manner so I drew a grid on the 12k and put it on the paper, didn't take a but a few strokes to get all the marks off. But I guessed as much when I set the thing dry on the granite table and it practically stuck to it.
    Didn't mean this to be end all be all but just my one experience today.

    Does anyone else have the issue with 320 grit sandpaper leaving the surface rough? I'm worried that having a rough, coarse feelings surface on a 12 will affect my honing...and would smoothing the surface with my thurry slurry stone take the freshly lapped surface out of true?

    Is this rough surface normal? Why is 320 recommended for lapping if it does that?

    you need to use wet/dry paper and if it is new go over it with something else to get rid of loose grit

    thats good for flattening it quick then you can use a higher grit for polishing it off
