ID of this Lance / Pike head

[thinreadline]

This was acting as one of the finials of a curtain pole in a rural cottage when I found it recently. It has very tiny broad arrows on it , but o/w I can see no other markings. I am not familiar with the pattern of head and am unsure whether it is a lance or a boarding pike head . Can anyone help ? The blade is 26 cm long from tip to the start of the langets . What remains of the shaft is wood not bamboo.
