Hoodoo,
I think the Yukon Pro Skinner has a bit more belly than the Stright Hunter... which I think makes for an easier time skinning and slicing. The handles on my YPS are very comfortable, and are quite slip resistant. I once field dressed 5 deer in one evening without resharpening the knife, and with no slip ups... more a testament to Bob's knife making than my skill.
Both knives would be excellent, though!
I have used knives with less belly in the past, and I have found that I need to be much more careful with them when slicing open the hide on a deer to field dress it.
In my mind the Yukon Pro Skinner is just about the perfect design for a hunting companion/knife. Very similar in shape to the style Townsend Whelen chose as his idea of the perfect hunting knife. I think the extra cost is worth it.
Ditto the other comments everyone has made about both Bob and A.G. Russell. Two stand up guys!
Hope this helps. Feel free to email me if you'd like more info.
Ron -- I'll be in the Upper Peninsula (Schoolcraft County to be exact). Born and raised there. Managed to find a nice piece of hunting property there a few years back... and we've become pretty good stewards of the land, managing it for the game. Some nice bucks have already come from the camp... one of my brothers shot his first buck there in 1993 (a gorgeous 10 point!).
Good luck to y'all this hunting season.
AJ
