Those are lovely examples of a very nice pattern. I have a friend who is an avid big game hunter and also a guide. He does use other knives, of course, but a 5OT is his main knife. He field dresses, skins and butchers over 100 big game animals a year. When in the field for deer and antelope, the little knife is all he uses until back home. Nobody I know splits the pelvic arch on big game anyway. And until the animal is in a place out of the dirt, its a bad idea to split the sternum. I always use the biggest knife I have around for that job. Anyway, your #5's are super!
