    I picked one of these up hoping it would help with making a nice polished/mirror edge. I tried this on a Mora and it seems much to coarse to do so. Any help or tips would be great. I was going to get a 8000 grit water stone but figured this should be better since it stays nice and flat. Guess I was wrong

    The diamond stones will need some breaking in.

    I find that though my EEF DMT(on the aligner kit) doesn't give a mirror, it makes it much, much easier to get a mirror when you go to the strops.

    1. Flatten a steel bar 12"x1"x1/4", reduces its height to 1/8". Make sure use the whole surface of the stone. I ruined mine by lapped a ceramic stone.

    2. No. My 4K waterstone produces more polish finish than DMT 8EE. Kitayama 8K waterstone will produce mirror finish - with mud+light touches will yield 10+K finishes.
     
  6. The EEF DMT won't quite produce a mirror by itself. Maybe a hazy mirror at best, and much less if the scratch patterns from prior coarser hones aren't completely removed. Following the EEF DMT with Dia-Pastes on strops (6/3/1 micron) would help, or by following with perhaps Fine/EF ceramic hones, then polishing pastes/compounds on strops.

    Wrong tool for the job.

    Waterstones work far better on Scandinavian grind carbon steels.

    Diamond hones should be used for high wear steels.

    Choosing the wrong waterstone will leave you in the same position. What stones are you using now? Brand? Grits?

    I have a few different kits. The spyderco, DMT coarse, med, fine, and extra extra fine, Razors edge coarse and fine kit, and a strop with black and green rouge. I had a edge pro apex but didnt like it much. I have no water stones so I am open to option there. I mainly want these water stones to put a nice polished mirror edge on my scandi knives. I have a Skookum Bush Tool and Spyderco Bushcrafter that need some help.

    I can get a 1K and 6K king that is double sidded, would you say that will get me to the same place? It seems that it will save me $40 bucks too if that will work.

    It's very much worth the small increase in price to get the Arashiyama stones. My experience with King stones was less than enjoyable, not to mention the are very slow even on basic carbon steels..

    Knifenut, I took your advice, I got the Arashiyama stones in the 1K grit and 8K grit. figured since i really want a nice polish I might as well step it up a bit and skip the 6K stone for now. Thank again for all the help.

    What 8k did you get? Should have stuck with the Arashiyama's they were made to work together.

    Kitiyama 8K..... It was 3am when I ordered it, I actully didn't realize it wasn't the same name till afterwards. It was one of thos things saying people usually buy this or that with this product, and it was the 6K you recommended or the one I bought. I can try and cancel still if it would be better. I just want to get a nice polished edge.

    Well, I was able to change the order before it went out. Thanks again brother for all the advice.

    Last question, how polished of an edge can I get with the 6k stone? Will I get a mirror edge edge on my scandi knives? And will I need a nagura stone for the 6K stone?

    They seem to think of it as good stone but not great for a highly polished edge. This is getting frusterating.

    For mirror finish many of different knives, I use KitAyama 8K (notice: the capital A) but for high density hard carbides knives sometime I need to use 1 or 0.5 micron CBN on balsa. CBN is smoother but I also use mono crystalline diamond 0.5micron on balsa.
