I've just ordered a Chris Reeve Shaddow III, for exactly this reason.
This is my choise, however there is a whole pile of excelent fixed blades of this ilk to choose from. We are spoilt for choise.
Fixed, also gives you more knife and reliability for your bucks. It is only our affluent society that allows best folders to even try to match fixed blade performance. Most reasoning for folders can be put down to life style, fashion, and changes to society attitudes, which have nothing to do with practicality. If you can carry it on a belt or in a large pocket then it should be a fixed. Fixed wins hands down.
Carry options don't have to be belt only. The nordic sheath that wraps most of the knife is nice for carrying in a shooting jacket pocket. A neck carry system is also realy practical. Ray Mears favours this type with a strap harness that has his knife rest on his chest/abdomen, handle slanted down. Here he can sheath his knife frequently during a task, rather than puting the knife on the ground.
