folks,
The only thing I would add to comments is that whatever you choose as your tactical(s), carry with it you always. Make it a part of your attire as you do underwear. (Okay, I DON'T want to hear about...

) It/they must always be kept in the same place(s) on you. You have to practice accessing them in different situations. If you don't do this, you will find yourself searching for them when you need to and unable to access them as quickly as the situation may dictate. That means they are practically useless... This is the same situation if you carry a concealed gun.

Depends on the type of tactical. With knives, especially folders, you have to be careful that quality is decent lest you have a knife that folds up on you own fingers or allows your hand to slide onto the blade in the critical moment. "Economical" but also dependable. This puts you in the range of
$60 to $200. An ASP (expandable baton), depending on size, goes from about $60 to $150. Mag lites go from $12 to $50.
"Economical" varies with the individual's circumstances. But, you need to ask how much is your life or the lives of loved ones worth. I have a friend who bought a cheap expandable baton. He had to use it. The thing bend and wrapped around the attacker's head and the guy was still standing. He ended up using effectively the butt end as a pommel. He bought an ASP afterwards. I've heard stories from FMA guys who said they were "sliced" by el cheapo knives and they didn't even draw blood...
>>A point that is raised over and over
but is so important is also to not carry around much less exhibit anything that you aren't prepared to use lest you end up wearing it...or worse!<<
This point can't be overstated. Look deeply before making that move. Like having a child, don't casually decide, "yea, I think I'll have one of those..." We are talking life and death.
