Katars with protrusion

[Jim McDougall]

Hi Trajan,
Thank you again for responding, with pictures! Interesting system using letters to 'catalog' (?) these weapons. I have often tried to imagine how it is possible to collect weapons without ever trying to learn more on their origin or age, but clearly these methods exist.
Nice exemplars, but how unfortunate to see them regarded without history or dimension.
I'm just sayin'

Jim
