[Bonetools] unknown object

[nejma goutas]

The Marta's objects are very similar, and especially what is most striking
is the resemblance of the technical traces on the underside. And I totally
agree with Christian on the assumption that the rough surface may be useful
for the better application and hafting of glue.

In this regard, there are some very interesting work (in French) by R.
Deffarges, P. Lawrence D. of Sonneville-Bordes (1977), as well Rigaud and
J. Allain (1986, 1989). This work concerns Paleolithic objects, but the
idea is the same. A. Rigaud and J. Allain have shown that the striations
made on the bevels of Magdalenian points were very effective in hafting of
these points. Even with a slight striation, the resistance to dislocation
passes between 40 and 45 kg after adding glue (Allain and Rigaud, 1989, p.
221-222).

Obviously the mechanical "stress" involved in the function of projectile
points is very different, but the principle remains the same: increase the
adhesion.
Best,

Nejma
