Skidbladnir

Skidbladnir ("Wooden-Bladed") was Freyr's ship, the most beautiful and best of ship ever made, created by Ivaldi's sons (Brokk and Sindri).

It always had a fair wind and it could be folded up at will and put in the pocket.

"In days of old | did Ivaldi's sons
Skithblathnir fashion fair,
The best of ships | for the bright god Freyr,
The noble son of Njorth."
(Grímnismál)

And a cool ship needs a really cool song:) ...
