I'll point this out to you because it doesn't seem to be all that obvious but you're mistaking Cold Steel's advertizing with what their knives are made for and capable of.
Your argument would prohibit people who don't own dogs from buying cars that are advertized as good dog carriers.
Cold Steel folders are intended and designed for the same market as all Kershaws, all Byrds, many Spyderco's, a few Benchmades and lots of other brands. They have their own style and design (which marketing emphasizes) but they're solid rugged inexpensive folders that come in all sizes. Cold Steel folders are in no way, in no sense of the word 'niche' knives, or knives intended for a niche part of the market.
If I made some video's showing Kershaws and Spyderco's cutting through meat filled boots (which I'm sure they could do), would that change their intended market? Of course not. It might make them appeal to an audience that until then was not interested in them though, just as - apparently - it turns off other people that would otherwise be interested in Cold Steel. That would be their loss, by the way.
A karambit is a niche knife. A 4" clippoint folder is not.
I'll point this out to you because it doesn't seem to be all that obvious but I'm not saying what CS's niche in the market actually is. My example was pulled from Gadfly22 and the rest was a jab at CS marketing. You can see where I used the phrase "such as", to show the statement that followed it was an example.
Are you intentionally missing the point or do you have comprehension issues?
My post was to explain to you that, right or wrong, Gadfly22's point was obvious and that his use of the term "niche" was fine. Whether or not CS's niche is poor people is irrelevant to my post. Yes, a Karambit is a "niche knife". Folding knives are a "niche". Kitchen knives are a "niche". Mallninjer is a "niche market". So what?
