My son and I drew out for cow elk this fall.  We are very excited.  A dentist friend of mine who hunts elk suggested I get a knife with a gut hook and a bone saw for the sternum.  My dad hates knives with gut hooks.  I currently have a Buck Vanguard with about a 3.5" blade.  The guide who works at Gunnies said the Buck won't hold an edge long and will be difficult to resharpen.
Any suggestions on what would do a better job for the knife?
How about the bone saw?
THANKS IN ADVANCE!!!   TJ
