I carry less - lethal options when away from the house, normally a can of OC spray. I don't plan on using it to fend of an attacker with ANY kind of weapon, be a knife, club, hammer, etc. I only plan on using it to prevent or end a bare handed assault by one assailant. If I face multiple attackers, or any attackers with any kind of weapon, then I should plan on defending my life with possibly using deadly force due to the attackers making it that way for me.
In home use of less than lethal is not smart in my opinion. When you are attacked in your home, you are facing a determined attacker with no remorse, consideration, or concern for your home and/or loved ones. Therefore, I only consider a firearm or firearms in my home defense option outside of locks, a fence, my dogs, etc.
