Thanks as lot for your coment and for the info, Freddy,
I also do varnish my piece blades, some times, to preserve them from rust.
But this one was much too shining. I have now oiled the blade and liquid wax the handle; it looks more discrete.
Thank you for the kind words, Lew.
So good you showed your nice example with the dots, which were a riddle to me.
By old, you mean 19th century ... or not that old
?
