Voi Kyrpä! butter knife (egg-butter-knife)
You guessed it, there's a finnish curse "Voi vittu!" and "Voi kyrpä!". As the word "voi" has double-meaning as a preposition to a curse (ie. Oh, in "oh, come on") as well as the word "butter".
These butter knives are made of finnish alder.
At 16 cm long, it is a bit above average...
