Antique Medieval 9th - 10th century A.D. Viking Warrior Spear Head

Superb quality antique medieval 9th - 10th century A.D. Viking warrior spearhead. This beautifully and extremely well-hand-forged steel spearhead has a sturdy, tapered, diamond cross-section blade chiseled on both sides with two narrow fullers.
The elegantly shaped base of the blade has a medial ridge cut on either side with chevrons and punched dots. The hollow shaft is conical in shape, with two ribbed collars at the mouth and a pierced hole for attachment.
The blade has a slightly visible fine vertical welded pattern (forging pattern).
This is the best quality Viking spear I have seen in over 50 years of involvement in the antique arms and armor trade.
MEASUREMENTS: Overall length: 27.5 cm (10.83 inches).
CONDITION: In original, untouched excavated condition, with nice smooth oxidation, partially corroded, but overall, in good condition considering its age to be over 1000 years old.
REFERENCES:
Most medieval Viking spears are badly corroded, but this particular spearhead is in remarkable condition.
