These look good, to me, mojjax. In general, celts ... but the smaller one has a curved bit which could suggest it was being used as an adze.
Don't usually try to ascertain authenticity through pictures alone, but there is plenty going on with these that makes me think they are the real deal.
That longer one ... does it have that flat edge on both edges, or only the one ? Also, if it's no trouble, would like to see the rounded tip on that one ... looking for use wear. This may be a celt, but, it could also be a multi-use tool.
