The archaeological excavations at Bryggen has given us a magnificent collection of runic inscriptions. We find trade letters, receipts, poetry, religious inscriptions, ownership marks and inscriptions with almost verbal utterances. This large variation suggests that runes were known and used by a large proportion of the population in the city during the Middle Ages. The runes contain mostly straight lines, so that they were easy to carve with a knife in a piece of wood or similar.
In the Middle Ages the runic alphabet, called Futhark, consisted of 16 characters, later 8 new characters were added.
You may find ‘r’, ‘u’ and ‘b’ written with more sharp lines, but this is just a brief example from Bryggen. Also, futhark may varies between cities in Norway as the dialect varies.
This is my attempt with futhark. You can try as well, if you want to feel like the vikings.
