These pics help get some idea of the thing. It is interesting how weapons all over the world have very similar sizes. The knobkerrie on the right is 313g the boomerang is 359g and the other knobkerrie is 372g. Even if it was used as a sword club it would be quite effective easily breaking a collar bone, damaging the face and even the skull. The maximum thickness is 13mm. There is some polish to the item, not like the 19th century knobkerries. I am happy with mid 20th century. No signs of use as with the knobkerries for all that matters, but that is not unusual on many items we collect
. The pics are interesting?
