[Bonetools] bone object ID

[Marianne Christensen]

Dear Steve,

I have been looking at your bone tool. It seems to me that the mark  
is very different from the one left by sawing with a string adding  
sand. Actually the groove seems to be too splayed and "uneven",  
though it is always difficult to identify details on a photo. I join  
an example of an experimental mark from sawing horn with a string  
adding sand, as you can see the groove is very straight with almost  
vertical "sides" and very regular.

I am not a specialist of late periods, but your tool reminds me  
something I have seen in relation with a lathe.  I am thinking at the  
part of the lathe, which allow to drive it, so the groove could be  
the mark left by the "belt" during driving (this could then explain  
the splayed aspect). The hole could be a part of the mounting system.  
It is just a suggestion!

Did you observe any polish or other traces in or around the hole?   
And what about the circumferential groove how are the marks inside,  
is it irregular in width?

Best regards

Marianne Christensen
