Scissor Dagger ??

[katana]

Hi,
was watching an antiques programme on UK TV and this item appeared described as a unusual pair of scissors possibly of Damascus origin.
To me it looks like a 'concealed dagger' when closed, the finger 'loops' forming a functional handle.
Thinking that I had possibly seen 'weapon' in a utillitarian house hold object, I did a few searches to find out ........that these do exist ie scissor daggers

A few screen shots below, has anyone any more info ? who used these....women for protection ? assasins ? .....murderous Tailors
