Excavated knife/dagger for ID please.

Looks like a clip point to me, something I wouldn't expect on a seax. In addition I've gotten the impression that it's the straight side which is the sharp one on a seax, whereas in this case the edge seems to be one the curved side (ie down in the first pic). The part about the blade-tang transition being a bit too well defined seems to make sense as well.
