Unless you have some very specific task in mind I daresay you will be disappointed with any knife like that. IMHO a knife should first and foremost be good at cutting. A beefy blade with a thick profile just plain sucks at that.

Second, you can put mean looking teeth on the back but if the blade is too short and thick (any kind of knife blade is generally too thick for a saw, let alone the "sharpened prybar" type) you will end up with a miserable saw.

Third, no knife is much good as a shovel. If you attempt to do any serious digging you will quickly ruin the edge, possibly snap the point. Plus it will take you a while to dig a hole of any size, many times slower than even a small shovel.

So to make a long story short, the big Rambo sharpened crowbar may look macho but in real life it tends to be useless.

For the same amount of money you could get a good small knife, maybe a Mora, then a good folding saw and possibly an axe. Or if you really intend to do much digging, the Cold Steel shovel, which doubles as a pretty good hatchet. Alternatively you could get a sawback machete. Still too thick for a good saw but way better than the Rambo crap.
