OK. I'm guessing that there is no way to dissuade you. I'll call you Ahab instead of Ishmael. You are on a quest to slay the great black pig with a knife. I will offer a few suggestions for your hunt based on personal experience.
My primary concerns for offering this advice are optimizing your personal safety, maximizing the respect paid to the animal and minimizing the animal's suffering. Some animals are prey species. Some animals are predator species. As it pertains to pigs, humans are the predators and pigs are the prey. Sometimes humans are killed by pigs or die in a pig pen in which case the roles are reversed or the pigs become the scavengers of humans. If you decide to enter this relationship with a pig, I would advise you to respect the animal and to minimize it's suffering. You don't have to listen to me.
I have had numerous experiences with wild hog hunts. I have not personally killed a pig with a knife but I have been a part of the hunts and have witnessed a few. My own kills have been with a Colt Anaconda. The ones that pertain most to you were part of the Amazon 5000 Expedition. In that case, the expedition was not allowed to carry firearms legally. Part of the expedition was foraging for food and wild hogs were occasionally encountered.
The method the expedition used is as follows. A wild hog is encountered - most frequently by smelling them. 4 - 5 guys get ready for the hunt. One guy scouts out the surrounding terrain looking for natural areas to trap the hog. Common natural terrain features that were used included rivers with muddy banks, steep hillsides etc. The guys gradually herd the pig towards the trap point. One guy is holding a tree branch, one guy is holding a knife. The team worked in concert by herding the pig towards the trap. Once the pig was in the trap, the guy with the big branch would whack it over the head a couple times. The guy with the knife would tackle the dazed hog and plunge the knife into the heart of the pig, meanwhile holding the pig down until it died. There was lots of squealing, lots of blood, lots of stink from the pig and lots of bugs. You can NOT make a mistake in this process or you will suffer the consequences. The pig does not want to die and it will fight you to preserve its life.
There is video floating around on the interwebs of the process we used, but the knife used was a BHK Pathfinder knife. The problems encountered with this particular knife were that the fingers of the stabber would slide over the blade because there wasn't a guard to stop that from happening. As a result of those experiences I worked with my expedition leader to develop a knife that would be suitable for long term expeditions and adequate for the daily tasks of knife use, but also include a guard that would not break and would prevent your finger from slipping over the blade as you stab the pig. None of these are commercially available yet. They are sitting on top of my forge waiting to be finished at the moment. You don't need one of my knives, just make sure whatever you use has at least a 5.5" blade and a guard. Max I would use a 7 inch blade. I won't explain that now, but 5.5" to 7" seems adequate and proven for the task of stabbing and killing.
If you want to do it right with dogs and pay your respects to the animal, I would recommend having one guy along with a baseball bat who will swing for the fences and stun the pig. Be prepared to then tackle the pig and stab it in the heart. I advise you not to go through with this, but if you decide to, give what I have said some thought.
