I got mine - I received the wrong one, I got the spike hawk but I ordered the tactical hammer poll.  Haven't decided whether to exchange this one yet.  It's pretty heavy for a hawk, it feels less like a weapon and more like something you'd use to tear down a building.  Sturdy!!!!  But not super-quick in the hand unless you've got popeye forearms, or perhaps are very practiced.
The edges are not sharpened, although that shouldn't be hard to do using sandpaper - not looking for shaving sharp on this tool, it would be too dangerous to the user I think, esp. with that incredibly wicked tanto spike!  A few chops on/into a 2x4 show how devastating this beast can be.  
The handle offers very good retention, I was surprised at how it is perfectly grippy without being abrasive, and it doesn't feel like aluminum really.  I think I would prefer the hawk to be a little lighter, maybe via more holes in the handle?  And instead of the handle end coming to a point, making that end a modified pry-bar.  
Overall this thing is an indestructible brute, so if that's what you need then this is an absolutely terrific value!  And the sheaths are indeed excellent; well-made, strong & versatile.  Overall these hawks appear to totally deliver as advertised, for an excellent price.
