I think that is the Swedish Fire-steel answer to a Jukkasticken.

Tip: The trick will all of the small ferro rod's is to place the end of the rod into the tinder. The trick of drawing the rod back against the knife only works effectively with the full sized rods.

With small sticks I always have plenty of Tinder-Quick with me. Saves a lot of time and frustration.

If you don't have T-Q's use cotton wool.
