OK Gorog.
I think that the guys for the most part don't want to offend you.
There's a reason those types of "fantasy" blades are made much (though you may want to look at the Bud-K catalog, they have a lot of that stuff. Problem is, it's usually 420 stainless and made for hanging on a wall, not using).
They aren't real practical. Fo one, they will be nearly impossible to sharpen in the field. For another, all the pointy stuff makes them look really mean, but it's also things that get caught on stuff and hamper your draw and swing.
Another problem is that, while having a sharpened back edge like on your drawings and some of the blades you've linked to may be good in a fight, they don't have a lot of use in the field and can outright hamper some activities (such as using the blade as a drawknife to peel bark and shavings). Knifes with two sharpened edges are also illegal in many places, and I'd bet Delaware is one of those places.
If you look at historical blades, very few have such a fantastical design, and those that do, like the kris dagger had their shapes as much for religious and ceremonial reasons as any functional reason. Plus, it's very difficult for such shapes to be made by a blacksmith. Even in the modern day of waterjet cutting and CNC machines, such blades are not used for combat much, if at all. People who are into blade martial arts who design their own "perfect" blade often come up with very plain-looking, deceptively simple, blades.
If you want something with a flair, and that is also a very good knife, despite a lot of internet bashing, go to
www.hogcult.com and look at some of the blades Jerry Busse has made (he also has a forum here on blade forums). Now, MOST of his knives are out of production (he only makes one or two models at a time), so if you want one that is out of production, the main source is the exchange here on BF, and the prices can range from several hundred to over $2000 for a single blade. I won't knock him, he makes first rate blades that do live up to the hype for the most part.
Now, to be honest, most of what I do, a kukri does it better. Even though he came out with a kukri like object, the ones I hefted didn't have the balance and feel that HI ones do, and I didn't care for them (which is a shame, I was really looking forward to an INFI kukri I couldn't live without) BUT, a lot of guys do like them, so. . .
If you are after "street cred" with wild designs, most people who know what they are doing will give the kukri respect (and most who don't know what they are doing for that matter). In Afghanistan, it's fairly well known that the Al Quaeda terrorists are scared spitless of the Gurkha and their kukri. Not to mention they have a long history under the Brits (the Gurkha that is) of being very brave fighters and their kukri are legendary. Recently there was the posting about a Gurkha (retired I do believe) that took on 40 train robbers in a 20 minute knife fight with his kukri -- and won.
BUT, I don't want to force you into anything. There's all kinds of knives out there, and any specific forum you go to will be particularly passionate about the brand there.
