I personally rely on a Fallkniven for my core blade. These are very robust knives. They are also decent cutters because of the Moran edge ( think of an apple seed.) I also make it a habit to distribute inexpensive, but excellent Mora knives throughout my kit. A good source is www.ragweedforge.com ( Ragnar's site has a wealth of information on knives and other fun subjects.) I would start out with something simple and inexpensive. People have used rather humble blades for millenia with good results. With experience you will know what works and appeals to you.
