While this discussion could quickly turn into one similar to the watch thread, I'm curious as to why you talk about hand protection with that knife?
Two points, in a survival situation (survival = living in the wild, etc), a handguard would protect from what, a tree limb or sharp weeds (serious question, not rhetorical)? From a survival standpoint, a large blade and handguard just add extra weight not needed. That said, a handguard may keep you from getting an occasional busted knuckle.
In a combat situation, if you're in a knife to knife engagement you're going to get cut, regardless of having a handguard or not. A larger blade/knife doesn't mean it'll protect you better or perhaps cut the other guy better, it just means you move a half of a second slower. "Dueling" someone else with a knife isn't going to happen, someone is going to get cut, chances are both will, and a handguard or large blade won't stop that.
For that knife, the blade itself is almost as wide as the handguard anyways, so it in effect negates the presence of the handguard. While somewhat useful, is actually a bit of a hangover from swordplay, when the sword blade could actually ride down the other blade and hit the person's hand, hence the handguard stopped it, plus it could actually be used as a secondary weapon too.
Not trying to bust on your choice, again, knives are a lot like watches, personal preference. Use whatever makes you happy and is of good, quality, construction. However, I've studied empty handed and armed fighting for years to know that I know enough to run away, especially if the other guy is armed and I'm not, to fight only if I actually have to. The size of the blade and the size of the knife only truly matter if the two people fighting have the exact same arm length, otherwise it's a moot point.
FWIW, I've actually had a knife pulled on me and I did run away, even though I had my trusty Emerson in my pocket. Not because I didn't understand knife fighting (I do, but am by no means an expert), but simply because I didn't want to get cut.
