I don't know Norwegian, but somehow I can read so far as "first post. Are there any [] here". Now I wonder what brunostspisere is. Translate says "brown cheese eaters" but not sure about if that's correct nor about what's brown cheese 🤔.
Anyways, what's on the picture is a tool we call "kaasschaaf" (cheese slicer) in Dutch. It can be found in every Dutch kitchen, we Dutchies love our cheese 🧀😋. Well, most of us at least.
