You can be sure it is Swedish, probably the grip is even Birch, with an outside chance that it could be coming out of Norway but these were not so common in Norway, anyway. As for these markings, the Christian cross is obvious but the initials within the stamps are often making reference in some respect or other to Christian devotion so not necessarily initials of the maker though that too is a possibility.
German inspired, maybe, I mean these are axes for carpentry work and the kind of carpentry work more common in Southern Sweden with post and beam construction, so that all fits together. Still I prefer to see it as Swedish. These Swedish are much lighter, making similar comparisons, than their German counterparts. Did you see my video, "The Ting Thing" loosely comparing Swedish and German axes?
