Hi Kronckew,
I did try previously to use a magnet....but it is very weak. Antler, I believe is an insulator and would therefor 'weaken' the attraction. Your idea of suspending the magnet is an excellent one

....I will give it a go.
Unfortunately all this detective work has only shown that this is a functional dagger. I think the origins will remain unsolved...never mind...I've grown quite attached to it
