I use a SCHRADE OLD TIMER. It is a lock folding knife with a 3 inch blade, 1 3/4 straight blade edge and a 1 1/4 serated blade edge, with a 43/4 inch handle made of plastic with a non slip type of coating, comes with a a heavy fabric belt holder that can be thrown in the washer when soiled. The curve in the blade is well placed for a index finger push down on the blade and also has a plastic piece mounted in the top back of the blade for gripping the the top of the blade. It holds a really sharp edge for a long time. I used it to remove fletching from a carbon arrow and then was able to field dress a deer without sharpening the blade between uses.
Heck I was on a outfitters hunt and the owner and my guide both had knifes for field dressing my deer that had dull blades so I handed them my OLD TIMER and they were both very impressed with the knife, they said leave it to the lady to have a knife sharper than ours[][&:]
My husband picked it up for me at Wal-Mart for $ 19.99, I love the knife and thought it was a heck of a good deal he got.
