If you bought a coarse DMT hone you would need to run the same course, though the opinion might be it looses its coarseness.
Bottom line, DMT stones need a break-in period and its not going to happen with one knife.
The EEF stone provides a very fine finish to the right steel (hard and wear resistant metals) but its not going to be a mirror edge, that's why DMT made diamond paste.
I know where you are coming from about the waiting for all grit stones. That's were my complaint comes in. I have spent at least 10 times the time and use of the EEF stone without the results I hoped for. I still can finish with the EF stone and have a very nice bevel. Then I use the EEF stone and the finish looks like I used the fine (F) stone again. I am completely confused about this. Maybe I'm doing something wrong but I can't imagine what. Once I askd DMT if there was a way to speed up the break-in time. They suggested rubbing my new EF stone (2x6" continuous) gently with my F stone under running water. I must have rubbed too hard because about half the diamond abrasive was immediately removed from the EF stone. They replaced it immediately. GREAT customer service. I decided short cuts can be a waste of time. Who knew?
I know, I should have.
I broke in that stone using the same knife I used on the EEF 4.25" stone with very acceptable results. After 20 or 30 minutes of sharpening the knife on the EF 6" stone the scratch pattern is now consistant from knife to knife. The time I spent is approximated as it was not in one sitting and it wasn't timed. If I were to have timed the amount of time I've spent on the EEF stone I know it would be 3 hours or more. I kept waiting and waiting for the scratch pattern to virtually disappear but it is still leaving a scratch pattern not consistant with any stone type called EEF. You are not the only one to question my resultes. I've questioned them myself, especially since you also are not the only one to have gotten much better performance out of DMT EEF stones.
The diamond paste was a real eye opener for me. It was the first thing I ever used that immediately saved me money in regards to sharpening. I was going to buy a new set of wood chisels because I couldn't get them as sharp as I wanted them. I bought the paste and watched the videos and when the paste arrived I had a set of chisels as razor sharp (or sharper) than brand new ones. Talk about happy. I knew I could keep them sharp also.
Anyway, I've used enough DMT products (bench, Aligner, mini, etc.) that I know what to expect as far as break in and afterwards. I'm just stumped by what I'm getting from the EEF stone.
The fact that I'm stumped bugs me more than anything to be truthful.
Since DMT already replace the stone once I'm convinced it wasn't a case of a "lemon" stone. I'll keep on working on it and see what happens.
One question. Do you think using water or dry makes a difference during the break-in period? I figured it didn't matter. I normally use DMT stones dry. I've used water on the continuous stones but not normally on the corrugated small stones. I'm open to any suggestions.
