Mike,
It will break. That's the bottom line. At some point the knife will be dropped, or used as a hammer, and Mr. Murphy will make sure it hits butt down on some hard pointy object. You're much better off with one of those small pin on compasses if you think you need a backup to your main nav. gear. Regarding the knife it self... Get it! The Mod.14 can get a bit heavy for normal camping/hiking. I think you will find the 5" more versatile and if you need something bigger take the 14. Either way you won't be unhappy.
