Mora's, they are inexpensive and razor friggen sharp out of the box. Easy to resharpen and hold an edge great. Bensbackwoods has a great variety starting at about $10 and up to around $30.
Did a wild boar hunt last fall, you are gonna have a blast, pun intended. Took mine with a Marlin 336 .44 magnum. Snuck up on the group and shot him from 20 yards, dropped that 300 pounder in his tracks. I would suggest 12 gauge or 44 magnum round.
