I often see SA R�hm daggers for sale and in collections, that has nothing left of the R�hm inscription what so ever, but are advertised as "ground R�hm"s. How can you tell if its a R�hm, if its not anymore? Is there really a way to tell it for sure? I own one, where the makers mark is partually gone, so thats not too hard to tell, but other ones, where the makers mark is intact? How do you know?

Rolm daggers, ground or not, often have a smaller maker's mark logo that is closer to the guard than daggers from the same maker but never inscribed with a Rolm inscription.

Most of the time, you can see some evidence of the grinding. Grinding that was done by the original owner, is often done crudely. Grinding done by the "factory" is often very well done and can be hard to see. For the later, you can often see a difference in the cross graining, dagger spine running down the blade is often a little off the original, and often some of the maker mark is ground off.

I am sure some of the SA collector's can give you more hints of detection.

A few of the makers used a smaller trademark for their Rohm daggers and many did not.

Who can listthe SA/NSKK makers who used smaller marks ?

Boker on SS daggers. Truthfully, if the inscription and trademark are ground competely off, you can't tell. If the TM or part of it is there, you may be able to tell. If there is part of the inscription left, you have to compare it to known authentic inscriptions as found in books, on this site, etc. It would be no trouble for someone who has a decent dagger, except for the reverse blade, to grind off the corrosion and trademark and claim it is a ground Rohm. There may be a clue it has been faked if the grinding looks fresher than the rest of the blade.

Gebruder Heller "Schmalkalden" had a smaller trademark for Rohm.

What about the obverse? The mottos on most R�hms(except Pack's for example) are more distant (about 1 cm) to the crossguard than on "regulars" . Nobody noticed that?

Take a look at these 2 different logos from the same maker AESCULAP. On the left is a regular SA dagger and on the right a fully ground R�hm. The logo on the R�hm dagger is smaller and closer to the crossguard. This is how you can distinguish a regular from a R�hm dagger ... at least from AESCULAP.

Also note Blademan is correct in saying the crossgraining on the factory ground rohm is different.
