The CS Rifleman's Hawk is an alternative. It'll cost you roughly the same as a Trail Hawk. Before deciding one way or the other between a Trail Hawk and a Rifleman's Hawk, try to handle one of each, or at least take a good, hard look at the weight specs for both. The Rifleman's Hawk head is a massive, massive piece of steel: the cutting bit is wider than the Trail Hawk's, the blade is long, and there's even a very significant amount of steel between the eye and the actual hammer part of the head. It's HEAVY. For a "car trunk" application, however, it might be just fine. For most applications, the Trail Hawk might be better--light, and with a little cutting bit, but with a little patience, it'll do most of what needs done. One thing about CS 'hawks: you WILL want to do some work on it before you send it out into the world. At a minimum, you'll want to do some serious sharpening--reprofiling might be more apt--of the edge. Myself, I always also remove the black paint-like finish from the head and the off-white paint-like finish from the handle, and replace them with cold blue and wood-stain-and-linseed-oil, respectively. Also, you'll want some kind of sheath.
One more thing, while we're here: for any car-based kit, you might want to give at least a little thought to the possibility that the user will want to carry the stuff by hand for at least a little ways. At a minimum, he's likely to be carrying it off road a few tens of yards to a campsite; at a maximum, it'll be nice to have the option of hoofing it out a long ways from wherever his car gets disabled. Therefore, it might not be a bad idea to put something a little more manageable than a milk crate in there to carry stuff. That might be an old day-pack, a duffle bag with shoulder strap from Wal-Mart, or whatever--or even a couple of different bags--but just a thought. For car use, I also keep in mind how things would look from the outside to a potential thief--for this reason, I tend to keep survival stuff in trunks, glove compartments, under seats, etc.--or to disperse individual components throughout the car, just so I don't have a tempting-looking backpack or fanny-pack sitting in plain view.
How can you go wrong with that?
