The absence of reference to standard specimens impairs both absolute values and error estimates, especially in chemical mapping. A Widmanst\u00e4tten pattern at a scale of 1\u2009mm cannot be revealed by chemical mapping with a step of 0.9\u2009mm and spots exceeding significantly the 1\u2009mm size. The presence of Ca on the hilt is probably an artifact as it can be observed on the blade and other objects as well. Finally, since the hilt and the blade may not be from the same origin, we have no clue about the origin of the dagger blade.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Albert Jambon MAPS, Version of Record online: 13 December 2022 LINK &#8220;Matsui et al.
