Thank you, Nils, Virgil, Henning and Christian.
I am glad that you like my knife.
Conserning your question Henning:
I had to look at the knife again and there is nothing. The explanation is light and shaddows.
The Pictures are taken in a conservatory (Wintergarten) with the Daylight comming from the right side of the Picture (Windows) and through the roof of White glas. On the left side of the Picture the conservatory is attatched to the house with huge windows acting as mirrors.
If you look at the tip of the blade you can see the same shaddows.
Best regards
