Defence Weapons Lethal non-gun

[Skvez]

Pistol crossbow. Useful for "stay back" threat, If I had to fire it I'd expect to drop it after rather than try and re-load (as effective range means an attacker would be on me before I'd had a chance to re-cock, re-load and aim shot 2).
So I also need some form of backup melee weapon for after using the crossbow.
Stick, baton, machete are all options.
Ideally a woman wants something with the range to keep the attacker (lets assume it's a man) far enough away that he can't grab us. If he grabs us he can use his greater weight to throw us to the ground and then it's all over.
For that reason knives, brass knuckles etc aren't ideal.
