A knife made from hearth steel. That is turn metal scraps into high carbon steel - end up with steel that could have been made in the Viking age!

@nielsprovos Would that qualify as a seax in your mind? If not, what would be the difference?
@aborigen yes. For sure. It’s a fairly broad category in my mind.
@nielsprovos Agreed. I was shopping for a seax, and many of them were longer with ornate sheaths, but the one I picked up looks a lot like the one you have pictured. I anticipate just using it for rune carving and maybe the odd meal, at a themed festival, rather than self-defense.
