Cheap durable knives. good to ragweedforge.com and look a the Swedish Mora's. Great cheap knife
middle of the road i use a buck fixed blade knife. There are so many in this catagory. Schrade sharpfinger, or a boker.
higher end, AG Russel makes some nice knives but i found a Knifes of Alaska S30v steel knife that i will try this year. I know this isn't what people consider higher end, but at $100 i think you can get a good knife. Just don't see the need to buy a $300 for dressing a deer. i see those as collectors.
Most of my knives are 4" blades or less with a 3.25 or 3.5" blade being my favorite. They must have a backbone to them. I don't care for thin blades that bend or give.
