High frequency of flakes for blank

Large cutting edge Extensive bifacial

retouch on whole piece

Plano-convex section Many typical cleavers High proportion

River cobbles and flakes of quartzite or quartz vein

Pointed tips are common Partially bifacial and

thick butt often unretouched

Thick body section Few typical cleavers Low proportion in

composition

Handaxes controversies; Chongoknian? Acheulean? or Acheulean-types? In Korea

How much similar to and different from Acheulean?

How old? Why the difference, if any? Any evidence of origin?

Quartzite/vein quartz
