Listen. You take a gas cigarette-lighter and you heat even very very
quickly an even little little dark part supposed to be birch tar,
and smell. If it's burned cork like, it's that tar.<br>

<p><span lang="EN-GB"> Unfortunately I cannot make any cuts on the
right black part of the artefact. But I attach
microphotographs of the surface, taken both in the middle and
in the area of right end. It seems that there is any coating
and the black something is something else (birch bark tar was
in use in the Middle Ages in this region). As you can see the
entire surface is highly polished and all edges are heavily
rounded, apart from the surface of “negatives” on the right
black end – there are scraping/whittling? traces perpendicular
to the main axis of the artefact, but only on one side. </span></p>
