What stone set for my tsprof sharpener?

Not getting great results from the included stones.

I’ll primarily be sharpening my German manufactured professional “s” henckel-zwilling kitchen knives.
 
Welcome.

Do you know what stones you have? Also do you know what metal is used in the knife? I am shooting blind here, but if the steel is a high carbide steel and the stones are silica carbide, they may not be hard enough to refine the stones. Also, a slower, medium pressure stroke will take off more metal than a fast stroke.
 
I think those are low vanadium stainless at moderate hardness. Well formulated alumina stones are appropriate. How much are you looking to spend?

Friodur steel
All our stainless-steel cookware is made of high-quality 18/10 stainless steel, which is composed mostly of iron with 18% chrome, and 10% nickel, giving this alloy its name.

They have a 57 Rockwell hardness

The stones I have are some diamond surface mounted on aluminum blanks

Diamond plates made with a galvanic bonding agent provide intensive metal removal and can be used for the cutting edge with significant damage (chips, bends, etc.).

The set of diamond plates on blanks includes:
— F150 Extra Coarse diamond plate is used for roughing of the edge and forming the shape of the blade.
— F220 Coarse diamond plate is used for shaping the cutting edge.
— F400 Medium diamond plate is used for main sharpening operations and creating of the aggressive/biting cut.
— F600 Fine diamond plate is used for pre-finishing of the cutting edge and removing noticeable scratches.
— F1000 Very Fine diamond plate is used for finishing the cutting edge.

These abrasives are much more aggressive than stones on organic or metallic bonding agents with the same grain size. It is achieved due to the protruding diamond grains, whereas grains of the organic or metallic bond get stuck in the binder and mixed with it. The grain concentration in a layer is 100%. At the same time, it should be noted that in terms of the duration of work, such plates will be inferior to plates on other bonds due to a thin layer of spraying, which is actively erased during the sharpening process.

Please bear in mind, if you work with soft steels (up to 58 HRC) these diamond stones will work out faster than if you use them for harder steels.
 
Make sure you use a marker to color in the edge to make sure you are reaching the apex with your stones. You may need to adjust your angles on the system if you are trying to keep the factory angles. It may take longer if you are reprofiling to the system angles. Some stainless steals, I find that alox stones leave a better edge. Make sure you are obtaining a bur on each side on the first stone before moving on.

Make sure you are looking at what is happening to the apex. Get a jewlers loup or good magnifying glass to see what is actually happening. Make adjustments on what you are seeing is the key. If you are grinding too far behind the edge you need to increase your angle. Too far to the edge, you need to lower your angle. This works for any form of sharpening.
 
I forgot to add that the fundamentals of sharpening apply to guided systems as well as freehand so you might want to read that as well. I need to revist that sticky above when i haven't sharpened a knife in a while. I just got the edge pro system after freehand sharpening over 40 years.

I could be wrong but 18/10 steel is ment for pans, pots, forks, spoons and similar. It has only 0.1 percent of carbon so can not be heat treated.
So, from where comes 57HRc?

Is Friodur the same as 18/10. I thought Friodur is more like 440c, but I'm not sure.
