Hi Fernando,
It seems the story hasn't ended
I've been thinking about the regular markings......
IMHO The marks on the axehead, suggest a single 'punch' with a very small rectangular end was used. Although they are almost arranged in a side by side configuration, in two parallel rows, it looks as if, each mark was done individually.
Notice how some are 'deeper', suggesting a harder strike on the punch. Sometimes the 'twin' of some of the marks are missing. Some of the marks appear to be struck from slightly different angles. Although fairly evenly spaced they are not 'exact'. Also noticeable is the fact that these marks occured after the hammer finish ...some 'cut' into the 'peaks' of the hammer marks.
Hopefully, the enlargement of Fernando's picture will explain better.
The other with the yellow oval, highlights an area which seems to be 'later' damage....its surface is 'different' to the rest of the 'hammered' surface and some of the 'notch' marks seem to have been deformed by the 'impact damage'
Regards David
