The Blackhawk SF dagger looks like a clean, no-nonsense design. That's a good thing. But it's primary purpose is killing. Anyways, I am just repeating what the others said already. It's not possible to baton wood with it, unless you are ready to ruin the edge from one side. It won't make a good rescue knife if you have to cut open someone's clothes and belts in an emergency. For many tasks it will perform adequately, for example as a steak knife it might be quite OK.
But hey, I've never been to Iraq or Afghanistan. If someone needs to go around and dispose of other men silently then this should be a good tool. I'm not an expert. I just wanted to pine in with my opinion on the design side of this blade.
To me it looks a little bit overpriced. D2 is a respected steel, it is a tool steel, it is used in quality knives but it's not a supersteel.
I am awestruck by the purity of this design. To me, this is a perfect utility knife. It is the Bob Lum fixed blade Encounter. It is 100% no-frills, no-nonsense, no-bullsh1t. It is a full-tang design: the handle and the blade are one and the same. The blade is pretty thick, 4.5 millimeters. The price is approx. 160 USD from Japan. It is made in Seki-City - possibly the place with the most knowledgeable steel masters.
I use Lansky Turnbox, a cheaper alternative to Spyderco Triangle. It works quite good with good steels (VG-10, 154CM, CPM D2), but I haven't tried it with supersteels like ZDP-189, which probably require something better.
I am only using two different knives one leatherman and one sami(native people) knife.
I dont need some tacticool operator knife and besides, the sami knife is way cheaper.
And the Sami is probably lighter, easier to sharpen, more user friendly, more useful... I could go on. My custom knives from you-know-who on this site (COUGHhenrysforkCOUGH), sheath and all, typically weight less than a military/survival/tactical/megaforce knife alone.
The Sami knives are interesting. In Finnish it's called "Leuku", and I have seen Americans spell it as "leuko". It has a scandi grind and it's bigger than an ordinary scandi knife. Sort of like a machete of the north.
