Ive built a couple of "pig knives" for local guys who would rather catch hogs than anything. They wind up using them 99.9% of the time to chop through a thicket, cut down a carry pole (after you catch a 400lb boar, you got to carry him out of the swamp somehow!), picking thorns out of there a--, etc....
These guys HATE to kill a hog, and i find most serious hog hunters are the same...they would rather catch than kill.
Any how, ive been a few times but still dont have the guts to get int there with a pissed off boar and grab him by the back legs, flip him and tie him.... Ide rather watch for now!!
