To HSO's regret, the tactical tomahawk hasn't left the scene yet, and there are more on the way every year. The market seems to be increasing as more of our soldiers come home, and LEO is made more aware of what it can do on duty.
But the question remains - what does the OP plan? The tool is selected for what it does in meeting the needs of the tasks - not vice versa, which is how most juvenile males buy things. They see it, it looks awesomely wicked and cool, has some aura of power or evil to it, and cash trades hands.
On the mature side of street, the adult male assesses his needs, then selects what features provide utility for tasks that satisfy the needs. What a tactical hawk can do is be light - which means you can carry it daily, but it trades off being a big chopper capable of taking down trees easily. A tac hawk has a spike, which can be used piercing, but it won't hammer, and you have to pay attention on the back stroke, just the same as hammering with the butt of a knife. The tac hawk has a fixed handle, which means it weighs more than one with a wooden handle, but it likely will never break. It also allows the tool to be used as a rolling pry bar with the spike, something a polled wood handle hawk won't do. The handle slipped thru the head protrudes and interferes.
It's unfortunate this pattern has been labeled "tactical," when in fact it just the venerable spike hawk of yore. If you consider it a handy, light, pioneering tool when backpacking a trail in wilderness, then a lot of useful things can be done with it to make a camp more comfortable.
If it's just another zombie slaying play toy, well, I agree. There's been too much of that. After Vietnam wound down the survival knife craze started up. Now that our time in SW Asia is winding down, I suspect the tac hawk might be the next long term craze for impulsive boys needed a testosterone fix. That doesn't mean that a good field knife wasn't needing, and it doesn't mean someone can't use a spike hawk effectively to fashion themselves a comfortable existence. But, it does mean some will hype the tool to an impulsive market who is looking for a badge of courage.
Well, you can't buy that, although some try at the PX.
PS, there is no "best" - that is a huge clue to it not being a tool selected to do a job, but a badge. The four hawks are entirely different with a range of features that do different things. The list of what needs to be done isn't real clear.
