I have owned two KOA knives; a fixed blade I gave to a cousin, and a folder I picked up in their store last time I was in AK. I used the folder for the whole two weeks I was up there (along with a W.C.Davis drop point hunter), and then put it away. It was a good knife, but most of my user's are custom, and I prefer to have a knife built exactly the way I want it to something mass produced.
I saw your thread on KaBar/KOA. I won't own KaBar; they scream "cheap" and the grips mostly suck.
Don't worry so much about the steel, look at the design and what you want the knife to do. I've never had a lot of reason to hack down forests, but have skinned a fair number of different critters; most people use a blade that's way too big. If you're going to save the hide you're going to want a slim blade about the size of your index finger with a drop point; what Bob Loveless would call a "caper" and a lot of mfrs call a "bird & trout". You try and get around the ears and nose with a blade over 4" and you'll be fustrated.
