In general, certain design features on a knife that is not clearly marked with a brand or a designers name tend to be found more on lower-cost knives. Not all low-cost knives are poor quality, but they tend to be simpler. So if a maker spent a lot of time making complex shapes, they don't tend to spend much on the materials (there is a wide range in cost of blade steels) and on heat treating (again, lots of variability on cost). If they do spend a lot of time, and use a premium material, then you would expect a premium price. Not always true, but in general.
To your knife specifically, you can see how the grind lines don't quite line up with the edge, particularly where the edge is recessed near the handle.
The saw teeth are cosmetic, this is another clue, as sharpening them is quite expensive.
While I will disagree with the the statement that "we know knives" as any sort of indicator of quality on its own, there is a lot of institutional knowledge here on the forum. But the first reply was a little out of line in my opinion. What you will learn is that if you find several knives that are all very close together in form, but under different brands and prices, it could be for a couple reasons. One is that it is a "classic" design that just works, and so many makers end up making a very similar knife. On the other hand it could also be that it is an original that has been copied. In either case its worth asking the forum "I really like the look of this knife, is there a legitimate and good production model, or what is the best-of-breed for this design pattern?" That will help you find the best knives for your budget, or avoid buying something that is a counterfeit or just poor quality.
While you almost certainly didn't buy a "good" knife, that wasn't your question, and we all buy cool stuff regardless of how "good" it is at one point or another. You will notice here that most of the members won't try to crap on someone's knife, unless they are recommending others buy it for a purpose it is not fit for, claiming it has qualities that it doesn't, or if it is a known counterfeit.
