Any knife for self defense requires a skill set of martial arts in depth first. If the user cannot successfully defend themselves in bare hand combatives, disarms, and reverses, they won't even be able to reach for their own knife. Besides, the opponent has graciously offered his, it's simply a matter of taking it.
If that sounds like a nearly impossible task, then carrying one in defense will be. The mindset and skill level are seeing something beyond their ability. Fix that first. On the journey to becoming accomplished in self defense, it will be discovered that the knife has offsetting disadvantages. They do exist - and are the historical motivations in invent handguns to improve on them.
In this day and age of more than 40 states with "shall issue" concealed carry, use of a knife as a weapon is now relegated to those who can't carry a gun. Whether it's the expense, or the legality is rather moot - guns can be had pretty cheap, less than a lot of knives. The Ruger LCP retails for $280, the Sebenza $350. And for the really cheap end, the "Jennings" pistols are still out on the gun show tables. They can function well enough for one shot.
The cute scene of Indy Jones pulling out his revolver in frustration at the sword wielding assailant was more than just some goofing around on the movie set left in by the editor. It's a statement of those skilled in superior weapons and why they are preferred. Don't fall into the fantasy trap that carrying a big knife will help much. Attackers do exactly that, come unexpectedly and from an ambush to prevent any response at all. Practice skills to resist that before even considering what weapon might be appropriate, and most of the problem is solved.
