The amount of splinters within the Jettböle assemblage is large, 60%.
This is valid even though the excavated material was sieved through
0.5 cm mesh, and even though no water sieving was conducted. The
original amount of splinters could therefore be somewhat higher
than shown by the excavated material. The 60% from JI99 can be
compared to the mere 28% from Bergmanstorp, trench 2.

The cores are mostly polygonal in shape and are the result of an
opportunistic strategy, where the toolmaker has used appropriate
platforms and has not tried to uphold or create a platform suiting his
purpose. Some cores have a constant platform. The relative frequen
cy of cores is higher at Bergmanstorp, where the 74 cores constitute
2.4% of the total rhyolite material. The corresponding value in JI99
is 0.4% (33 cores).
The overall impression after the survey of the material is that there are tech
nological similarities. Judging from the cores, which are often exhausted,
