Guksi

I got my fiancé's birthday gift ready. I burned that pikeperch design to it. So, yes, I'll give him a guksi (or in Finnish: kuksa) which is a type of drinking cup traditionally duodji crafted by the Sami people of northern Scandinavia from carved birch burl. I didn't carve it because I don't have tools required for that - I bought it.

Taking kuksa to use you have to do a "Guksi's initiate" or kuksan huljutus. It's a tradition and this is what you need to do: you pour coffee or cognac (or whatever you like) to your kuksa so that bottom is fairly covered. Then you have to rotate the kuksa in counter-clockwise so the liquid will rise to the edge - but don't spill it! Now, drink it up.
Then you do that same thing but now in clockwise.
Third filling you can take the amount of your drink as you like.

When you clean your kuksa - don't use any detergents or you will ruin your kuksa. Kuksa is ONLY cleaned with moist towel or under a clean water.
One Lappland-ish belief says that if you wash your guksi you can lose your luck: only rinse in mountain streams is allowed.
