yep

 When I was at the archaeological museum in Gomen (Kochi), they
illustrated how microblades were used in a construct.
Rather nasty looking spear, probably designed more to cut through
thick hair and skin by jabbing and twisting in order to cause massive
damage. The microblade tools were probably specifically designed for
hunting Mammoth and other arctic megafauna.
  
  Conventional blades would have been put on a halfted shaft and tied
with some sort of an adhesive. With microblades almost certainly an
adhesive with qualities in an of itself to hold the blades within the
slots was used. In the region where these were found a developed
laquer industry had also developed later so it is possible that tree
saps were used as adhesive.
  Given its sophistication its spread may have been linked to
specific cultures, and, at least in Japan, given the cultural
complexity due to multiple immigrations this seems likely.
