What you plan to do with it needs spelling out. There are very specific reasons different tools have different shapes, and while they can be versatile and get a lot done, they can also be frustratingly limited by that shape, too.
When you have an idea of what the tool does, then off the wall suggestions from fanboys sort out quickly. It's like asking for a breaching hawk and getting the usual "my Estwing carpenters hatchet can do all that and it has a hammer head and nail puller, too!" No, it can't - when you need a rolling head pry bar action, you can't use a short handled hammer poll hatchet. Tools have specific shapes for specific tasks.
Then you get into how much you really want to pay for it. Would some of us love to have an RMJ Shrike, sure. For the difference between that and a $60 hawk, tho, I could buy two or three ESEE knives. If I was on duty and in combat where I needed it, the Shrike would be #1. At home, with other responsibilities, plus other tools at hand, not so much.
List out the tasks, then sort out what specific features you need to do those tasks. If you need to pry, you need a spike, if you aren't trying to literally poke holes in things, then it can be square profiled with no sharp point (to bend or break off. Hmm.) If you need to pull a nail, ok, can it be done with the other end of the handle? Some hawks do that. Chopping wood more than metal doors, etc. Long straight handle for leverage vs. short for portability. Go too short, and it's really a hatchet, not a hawk. You lose the leverage and impact of a longer swing, which means the head can be lighter for the same affect - and less work carrying all day.
Once all that is listed, then you look for a hawk that has it, or, can be made to. One of the fun things to do is modify a tool to your liking - I've already ground off the tipped up bit on my Condor, it rolls better levering now, and removed the paracord for a better fit. It's less problem than butchering up a high end hawk to lose resale value, which some consider important. Goes to why they are really looking for one, it's more show than tool.
Get an idea of your tasks, what features you need to do those tasks, then go shopping, and don't just grab the first cool one that comes along. Stick to your list, and you have the better tool, albeit not always the one that everybody thinks is cool this week. It will be something else next week, anyway, and you will still be using a good hawk then, too.
