Google translates snibbskål as "ear cup" my Swedish friends told me snibb means pretty much the same as tab in English, it can be the corner of a piece of fabric, anything that sticks out or an ear lobe (ears were also nicknamed tabs when I was young). skål means bowl, it is also the standard toast when drinking alcohol and the link between bowls and drinking is strong.
So here are a collection of bowls with tabs, the ones normally reffered to as snibbskål are the square pair in the middle with 4 tabs.
the profile is very sweet, a simple humble bowl that someone has eaten breakfast or soup from for many many years I love it dearly.
And here a Swedish bowlturners lathe just like the old British ones.
