I read a post about "best fighting knife" and a guy linked to video of a guy using a "karanbit" - a very curved knife from the SE Asia area. I'd first seen this type of knife when Spyderdco came out with one, and never thought too much about them - looked far to curvy to run someone through with it, and sort of goofy.
But the price was right on eBay for this one - 65 bucks and it was brand new, so I ordered it, and it's nicer than I would have thought. Pretty nasty looking as well.
The Steel Tiger!!! This model came out in 2006, and by then you could see the writing on the wall for Cold Steel. While they still sold their classic lineup of knives, they were starting to offer a huge number of other models, many of which looked like ones you'd get at a flea market, or from Ninja ads in Shotgun News and such.
Interestingly, before I bought this one, I don't know if I'd ever seen one on eBay before. Now, there are 3-4 of them for sale, and I'd seen such batch sales before - you see a bunch of the same models for sale at once. I'd theorized that it could be that counterfit models are made in batches, and then sold in the same time frame. Others have said it more a matter of once a few versions sell, then other vendors have an idea on the price and demand and offer what they have in stock.
It's why I always try to see if the seller is an individual, or either a huge volume seller of random items, or has just a few sales. That said, there's only been one fake CS knife I've bought on eBay. The funny thing is that why it's a counterfeit (I think) Outdoorsman, I sharpened it up to as good as edge as any of my other knives, including the real CS ones. So while counterfeit, at least they used good steel it seems.
