Grog, yup. BUT sometimes you can't carry a firearm in certain places. Having a knife is better than not having anything. I personally have ended an altercation before it started just by having a knife suddenly appear in my hand. Are there better choices, YOU BET. BUT having something besides bare hands does give you a one up at times.
