Elk knife

[Baylian]

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
