Sir, That would be the Scandinavian Forest Axe.
GB is the only company I know of that sends their splitting wedges with a sheath, because they are sharp enough to cut you if your not careful.
In case you don't know about it already, please visit www.oldjimbo.com. Lots of good info on woods tools there. GB finally came out with a full sized American felling axe. Don't know how good it is, but they deliberated about it long enough.
Regards, Jim
