Thank you for the input. It might. I was wondering why you would think of a cherry blossom? Have you seen a similar stamp elsewhere?
At first I really thought it was rust, or damage. But, having seen the exact same 'thing' on another blade from Kanetomo (unfortunately I didn't save the picture) and on the exact same location (mune between 2 inspection stamps) and from the same year (Showa 17) I just can't accept it to be mere coincidence...
I'll keep looking...
After endlessly browsing through the net, I finally found an example of the little marking I found on the mune, on a different blade.
Of all places, I found it in this topic.
I am sorry, I didn't know how to 'quote inside a quote', so I hope this will lead you to the correct post: zentsuji2, on 04 Mar 2014 - 10:35 AM, said:

The small mark/stamp(?) is exactly the same, so there is definitely something there. However, it is not in the same spot on the mune, but between the arsenal stamps. Also the smiths are different: Kanetome vs Kanemoto. And, mine isn't star stamped, but a good candidate to be gendaito.
It would be interesting to know the date of Ian's blade...
Looking forward to your input,
