Between 1900 and 1960, in the cultural-historical paradigm, every archaeologist with respect for himself should know the various types of archaeological artefacts. In 1885, Oluf Rygh wrote a now famous book/catalogue called "Norske oldsager" meaning Norwegian artefacts. There, every (back then) known type got a drawing and a number. Rygh nr. 76 is a heartshaped flint point, and the original point which were drawn had been found very close to my native district, Kviljo.
So I made the point and fitted it to a shoot shaft with sinew and pitch.
