You sure did an excellent job finding out the correct English term earspoon (German:
böhmischer Ohrlöffel) - brilliant
That type of sturdy hafted weapons was of course both the follower of the Late Carolingian
Flügellanze and the ancestor of the famous
Friaulischer Spieß (English equivalent urgently sought ...), with its robust down curved side hooks!
As Thilo superbly pointed out, it obviously did matter in terms of stability whether the straps were fixed on the broad or on the small side of the socket!
Thilo, could you please post a few images or line drawings of those two differing ways of strap fixing, as those are esteemed very valuable by me concerning later hafted weapons like pikes and halberds? Thanks a lot! I'd come on in right after with never seen actual material.
Best,
Michael
