I bought one of these last week. It's called the Zambezi.
The blade steel is 440-c. The blade and edge is as thick as a Cold Steel SRK on steroids.
Before I proceed with my initial impressions of this knife, it is only fair to tell you I've not done any cutting tests with it yet.
The sheathing system is a black ops operator's dream come true. For the everyday person like me, it's more like a nightmare. After you get the bloody thing on, you feel as trussed up as a bondage bitch.
The sheath claims to be Kydex, but it does not look or feel like the Kydex I use or get on other knife sheaths.

It also takes a bit of practice at un-sheathing the beast. You have to fully depress the button located under the sub-hilt before pulling the blade free. It sounds easy, but it took me quite a few tries before getting consistently good withdrawals. The sheath does not work really well without tying it to your leg either.
The edge

was soooo highly polished, it would not cut or even shave hair. They polished the edge right off. After re-establishing the edge on a ceramic stone, it was scary sharp but the thickness of the edge still is not what I would consider "high performance". Too bloody thick. Don't even think about using a Sharpmaker on this edge. The edge angle is 25+ degrees.
The knife is basically a stainless steel sharpened pry bar.
The good thing about it though is the handle. It's fairly comfortable. You can choke up on the handle and get a sub-hilt advantage out of the handle. Move your grip behind the sub-hilt and you still have a handful of handle with more leverage for chopping and the sub-hilt becomes the main guard. Pretty cool.

Please refer heavily to the pic that el cid provided to see what I'm babbling about.
If you are an actual operator, or want the same type of equipment that a CIA operator or Navy Seal may have, or your a ninja death-mongerer, into bondage or just a gadget freak kinda knife person, this knife is worth a closer look.
If you like your knives to be like sharpened pry bars, this knife is most definately worth a look.
If you are two or more of the above, this knife is a serious "must have" item for you.
Rotsa ruck GI!
