Just asking for my sister-in-law.  She wants a knife to carry for protection since she has no firearm and I told her that a knife is better than harsh words.

Thanks.

Alright, but i suggest you get her a gun and training.  any resistance is better than none, but it's way harder to defend yourself with a knife, especially if you are untrained.

The only thing you can't carry in SD is a ballistic knife.

I don't think a knife is a great weapon for a woman. She would probably be better served with some good pepper or OC spray.
