Hi Jan,
The knife looks German, c. very late 19th century - early 20th century.
I'm not sure whether UchatiusBronce is a trade name or simply an
indication of the metal alloy used in the blade. Baron Franz von
Uchatius (an Austrian) invented a new process for making steel (Uchatius
Stahl) in 1856 and steel bonze (Uchatius Stahlbronze) in 1874.
