Stones dish out, is there any way to maintain them flat?

Diamond sharpening products can lose their diamond, which are the least likely to do so?

There are hones for sharpning stones. May help you.

Heard of a method Japanese chef apprentices use to to flatten their hone. Use a rope, tie one end around to the dished hone tightly, and tie the other end to your waist belt. Then jog around... not necessarily on your feet, you can ride a bike either.
Then the Mother Earth will do the job for you.Though the surface may not be as smooth as a mirror, it gets flat enough.
Take care not to let the stone rolling on the ground or it will chip off.

I believe it works on you also, but I have to admit when you do this you'll look very SILLY to all your neighbourhood that I hesitate to make this more than an information for you.

I use a 8" DMT to flatten other hones which are japanese waterstones but I think could be anything but diamond hones.
 
Secure a piece of glass to a flat surface.
Use spray adhesive to glue silicon carbide
wet\dry sandpaper to glass.Pour water on paper , rub the dished stone on the paper untill it becomes as flat as the glass.I do this with new stones ( Arkansas ) because they are rarely flat even when new , as well as cloged used ones I buy at sales to restore cutting ability.Start with 220 grit or lower and finish with 400 or higher.
I also use this method to flatten heat sinks
before attaching to processors for better contact thus heat transfer.
 
Eye,
I do all my sharpening of my belt grinder, buffs and strop. BUT, I can tell you this!
I use stones and diamond hones on a daily basis at my machinist job. Sharpening knife blades is butter compared to what I use these for at work!!!! I have used every availble diamond stone including the ones that come in the knife sharpening "KITS". For my use, touching up punches, dies and carbide cutting tools I need one that lasts the longest and wears evenly. I have found that DMT's line of diamond products to be outstanding. At work we use the two finest textures and have them all over the shop! No one uses the "Stones" any more for anything. I carry the small fine one on my keychain for touching up kife blades away from my shop!
With the way the diamond works I can't see using anything else!!!!
 
to reestablish the flat surface on stones, put some sand on a level concrete surface, I use my garage floor. Just rub back and forth a few times to get them flat. It helps to do this more often rather than wait until they are severe. Works well for me, YMMY.

What? Another knife? Don't you have enough of those things already?
How many does one person need?
And just what are you going to do with this one that you can't do with the others?
What is the purpose of all these knives anyhow??

 
I haven't done this yet because I rarely use natural stones, but SDs method is the one I was planning to use. Although GONESAILING's method looks interesting.

As far as which diamond hones keep their stones the longest... So far, I've been very pleased with my DMT stones, and not as pleased with my Eze-Lap diamond stick. I have heard the exact same feedback from numerous people. On the other hand, Mad Dog recommends almost any diamond hone except for DMT, so there are definitely differing opinions. For me though, it's DMT or nothing.

I have used the sand on concrete method for 20 years, with great results. Recently I tried alminum oxide powder on a piece of glass with some water. It works better than anything I have ever tried. I just leave it on the glass and put it away until I need it next time. I have done at least 20 stones with the same small amount of powder I started with and it is still cutting. You need to call an abrasive co. to get the powder, you may fint it at a industrial supply co.
 
Silicon Carbide wet belt on a surface grinder does a fine job of flattening stones if they are fairly far gone. If they are just starting to dish out a regular belt sander (stationary type) with a SC dry belt will do fine. Just be gentle.
 
I have had the same experience as Joe, seeing DMT's outlast Ez-Lap stones easily. I have heard 3M makes an even better product from a poster who has compared them to DMT but I have not used them. They are more expensive than DMT's the last time I checked.
