Yous guys is so lucky, gettin' ta hunt hawgs. We ain't got any round here, and I can't afford the travel, time, etc. of goin' after 'em.
When it comes to designing a blade for the purpose, I'd just as soon call up Larry Harley and get his advice. I ain't tryin' to set him up on a pedastal here, but the man has been refining and experimenting with his stickers on
thousands of hogs killed. He aught to have some valuable insight. I remember him saying "two edges kill not twice as good, but ten times better". (well, except his spelling ain't so good.
) He liked his blades to be very wide, since that's what makes the wound bigger, and he wanted the edge(s!) to go all the way to the hilt with no choil. That way when the blade is buried deep in the critter, you can lever it around. There's of course a lot more, but these main ideas really made sense to me.
I hunt critters with a knife, but since my methods are very different than the hog hunting discussed here, there are probably very few things that would translate over.
