A high-quality wooden shaft is recommended for the Viking spearhead, with ash wood being particularly suitable due to its stability. The shaft should have a diameter of approximately 23 to 32 mm, matching the inner diameter of the socket. For secure attachment, the spearhead features a long, slotted socket that is pushed deep onto the shaft. Before use, it must be ensured that the spearhead is firmly in place; historically and functionally, it is often secured with additional fasteners or by firmly screwing and tightening.
