I carry a good firearm 24/7. Dress heavier with a 1911 in .45acp when going to town. As an older man, I always felt a missing defensive tool. The sword.
A sword can is already in the hand when you need it. A sharp and lively blade will dispatch a threat as surely as a gun. 22 3/4" blade, 1060 High carbon, spring tempered and a good edge holder. I have sharpened it to a utility edge to cut but not roll on a bone strike. Will shave hair from the forearm.
Can choose to use the flat of the blade as a bludgeon or the edg as a cutter. the point will effortlessly pierce the body of a bad guy.
Now that's a knife.
