    Default Brand new DMT 325 vs Brand New Naniwa 12k. Not a good combination?

    Ok, so i just bought a brand new DMT 325 plate, and lapped up my 1k, 4k, and 8k norton stones, and they feel perfectly flat, definitely the smoothest Ive felt them (disclaimer, my honing ability is still pretty negligible, I've 'honed' about 4 razors, so the experience i have with these stones is still pretty small :P). So Ive read a few threads about a DMT 325 against a Naniwa 12k, some people said they had issues, some people said they had no issues. but I definitely had an issue. my DMT scratched the crap out of one corner, but worked well on the rest of the stone. Heres a picture.

    So my questions is if i should try again, or try something else.
    Just as a side note, I would just like to say that my previous lapping method was a granite stone, and a 600 grit sandpaper. On the 1k, 4k, and 8k, the DMT feels vastly superior!

    Thanks!

    UPDATE: I have discovered that this has been done this to all my stones in the exact same place, i just didnt notice at first, because the gouges weren't nearly as big the 1,4,8k nortons. So I'm pretty sure its the DMT?

    Did you remember to "break-in" the DMT-325?
    You can have everything, and still not have enough.
    I'd give it all up, for just a little more.

    I have read the 'users' manual and it says it might feels rough at first, and will 'soften' after use. I am not aware that there is an actual method to do this? Any help would be appreciated.

    I took a steel bar and rubbed the heck out of my 325 DMT and you will feel a big difference. What it does is knock all the high diamonds off. You are not going to hurt the DMT trying it believe me :<0) All that said 325 may be a little ruff on your Nani . Go back to your old way on that stone.
    Good judgment comes from experience, and experience....well that comes from poor judgment.

    When my 325 was new I used an edge (not the point but the shank I guess) of an older phillips screwdrive to 'burnish' it a bit. Not too heavy of pressure, and it worked pretty good.

    Had to give my DMT 325 a couple of the razor shank treatments and now she is fine even for the 12K Naniwa.

    The instructions are for using it as a knife sharpening hone.
    I ran mine over the metal edge on the bed frame several times. Worked well.

    That damage isn't about breaking in your DMT. It has a high spot. Judging by where the stone is scratched it could even be a high edge on the DMT. You might need to give the offending area a light tap.

    I just updated the original post, but ill put it here to make sure everyone sees it. I just looked closer at all my stones I lapped, and noticed that the DMT gouged them in the exact same place like that, I just didn't notice it first because on the lower grits (1,4,8k) the 'scratches' arent nearly as deep.

    Im not sure id be willing to 'tap' my DMT as to make it straighter. Firstly, if it is out, there will be no way to accurately guage if i get it perfectly straight, completely defeating the purpose of having the stone IMO :P, and with the plate being as thick as it is, I know I would need to hit it pretty hard. Should I email DMT about it? (assuming its not a break in issue).

    I did use a shank of a screwdriver as everybody suggested, but it made the problem negligibly better. I have a steel bar in the garage I could possibly use...
    Thanks for everybodies input!

    I simply sharpened a crappy kitchen knife on mine until it lost the 'sparkle' and had an even grey tone to it.
