Hello those of you who know about screws...
I'm looking for a type of wood screw. It is threaded at one end, then a bit without threads, and ends with a flattened end with a hole in it.
What is it called? At which store might I find these?
My somewhat rough sketch:

 

[useless]

Leaf screw.
Available at all building sheds.

Could it be bladskruv you're looking for? Like this one (just took the first best google link with image, there are a few variants):
