handbag = weapon ?

I changed my idea again.
I hope it will be the last time saying this.

Women's handbags are sometimes used as a weapon to hit people in a 'fearful' situation.
(fearful situation - thief, murderer, pedophile and etc)
When I make a bag I will be focusing on to the weapon function rather than a beautiful appearance of a bag.

Questions for myself :
- one effective weapon function?
- will the it be heavy? or light?
- survey on what the females put in their bag
- bag strap length?
- bag material? (heavier/harder material will harm more)
