Imperial navy dagger, help indefinitely personalized name

[messia]

Hi to all . came across such an interesting personalized dagger, can you help me find where to find information about the owner?

I am also interested in the image of a trident and an oar on the Dagger blade, does this show that this is the so-called «annual» dagger?

Hi,
so called “annual” daggers? Which daggers do you mean? I see a standard etching motif here.
Best,
Oleg.
