Locking your guns up is a wise precaution, but not keeping at least one out for social purposes makes as much sense as a screen door on a submarine. I also want to be a fly on the wall when any of ya'll try to explain to the DA why you hacked some poor fella to death with a khukri when you could have stood back and ventilated him with shotgun. A knife, any knife , is too personal for in house self-defense. Like someone else said, keep them out of reach. Make sure they're dead and there will be only one story to tell.
