Properly heat-treated 80CrV2 is one of the better carbon-steel alloys for knives, it's plenty tough, cuts well, and sharpens easily enough. And Winkler knives are known for very good heat-treatment But a knife is more than just the steel it's made from. Not going to get philosophical here. Just look at how many Winkler knives are out there being used, whether in war zones, hog hunting in Texas, or in deer camps all over the country. If they didn't cut well, they wouldn't be so well-respected. I met Daniel and his wife back when they were wearing buckskins and furs, and riding high on the success of Last Of The Mohicans. Nice folks, beautiful knives, and extraordinary leather-work.
That being said, the overall design of most Winkler II production knives, with the high flat grind, tall blade profile, and ample belly, should provide for more than adequate cutting performance. They''re mostly mid-sized working knives, for harsh conditions and usage. No, they won't likely do as well at fine detail work as, say, a White River M1 Caper. But I wouldn't think of using the M1 as a draw-knife, even in an emergency. I might, with a Winkler!
I had considered the Blue Ridge Hunter, myself. I'm still considering it. It's about the same size as my EDC White River Sendero Classic, and roughly the same price. It's much thicker, .210" for the Winkler vs .130" for the Sendero. Carbon steel vs stainless was not a major consideration. I went with the Sendero because I wanted a thin blade. But do appreciate a SOLID working knife. The Winklers are all that.
