I can't see why the traces of contact with an acid would not be more evenly distributed. Because the pits are so closely associated with the polish, the two kinds of wear must be associated with (and resulting from) contact with a same and unique material, probably a hard material instead of a soft one, but which one?

The tool has a pointed end with a wide angle (see image in attachment: it's specimen No 2). Because of that angle the pointed end seems too large to be used efficiently as an awl. Moreover, it does not have the "typical" leather polish, i.e. rounded polish that follows the micro-topography of the bone, with long, parallel and deep striations perpendicular to the long axis of the tool. What we see on this tool is different: a very intensive and domed polish, very bright, but apparently limited to higher points of the micro-topography: it does not extend down onto the deeper surfaces, and this could indicate that the tool was used on a hard material. The tiny pits in the middle of the highly polished surface are also unusuall; it kind of reminds me of comet-shaped pits visible on stone tools used on wood or silica-rich plants, but I have never seen anything like that on a bone tool (perhaps only because my experimental experience is somewhat limited...).</div><div dir="ltr"><br clear="none"></div><div dir="ltr" id="yiv4424858008yui_3_16_0_1_1420556962393_35479">Christian<br clear="none"></div><div id="yiv4424858008yui_3_16_0_1_1420556962393_28233"><span></span></div><br clear="none"> <div id="yiv4424858008yui_3_16_0_1_1420556962393_28237" style="font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:13px;"> <div id="yiv4424858008yui_3_16_0_1_1420556962393_28236" style="font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande,;font-size:16px;"> <div dir="ltr" id="yiv4424858008yui_3_16_0_1_1420556962393_28235"> <hr id="yiv4424858008yui_3_16_0_1_1420556962393_28234" size="1"> <font id="yiv4424858008yui_3_16_0_1_1420556962393_29831" face="Arial" size="2"> <b><span style="font-weight:bold;">De :</span></b> Genevieve Lemoine <glemoine@bowdoin.edu><br clear="none"> <b><span style="font-weight:bold;">À :</span></b> "Mailing list for archaeologists of the research group for the study of object and waste of bone, antler. ivory and horn." <bonetools@listserv.niif.hu> <br clear="none"> <b><span style="font-weight:bold;">Envoyé le :</span></b> mardi 6 janvier 2015 13h02<br clear="none"> <b><span style="font-weight:bold;">Objet :</span></b> Re: [Bonetools] Usewear on a bone tool<br clear="none"> </font> </div> <div class="yiv4424858008y_msg_container" id="yiv4424858008yui_3_16_0_1_1420556962393_28241"><br clear="none"><div id="yiv4424858008"><div id="yiv4424858008yui_3_16_0_1_1420556962393_28240">

<div id="yiv4424858008yui_3_16_0_1_1420556962393_28242">What sort of tool is it? Edged? Pointed? Most of my images are not digitized, but I have attached one with a similar pattern of a fairly high polish with fine striations in multiple directions, from an awl-like tool at Gupuk (Nits-1). At the time (a long
time ago now!) I thought the polish looked pretty typical for an awl, but the striations did not. The striations are similar to those on sinew twisters from the Mackenzie Delta, but the polish was different. Ultimately it ended up in the unidentified/multi-use
category. Not hugely helpful I’m afraid. Time for more experiments I guess!</div>
