obsidian as main material, but flint increasing; continuity in the use of bladelet blanks, higher frequency of cores, chips, flakes --> the obsidian was imported not only as semi-finished tools, but also as small or large blocks or flakes that were knapped within the site; 
main tool groups: pointed bladelet, fragmented points (mostly reshaped into other tools), blades of various shapes, sizes and types of retouch;

flint blades were rare, but there were more flakes than in the Early Neolithic; medium to large flakes often constituted the blank for ad hoc tools (e.g. denticulated pieces, scrapers); cores and core fragments indicate on-site knapping
flint raw material: mainly coarse grain yellow with thin black inclusions, rarely fine grained reddish brown flint;
the edges of many retouched small flakes and waste were glossed;
two glossed tool types: the ad hoc glossed tools out of coarse local flint, glossed blade blanks obtained from beige flint (probably not local), maybe used for harvesting (sickles) and threshing (threshing sledges or tribulum, with sets of flint flakes)
