There is no comparison at all. To use an analogy, you are talking Old syle Volkswagon Beetle compared to a brand new modern day Lotus.
I hope you did not buy it. Or I hope you like real cheap knock offs. Makes me real mad when a person in this country goes through all the trouble of the design process. patent process, manufacturing process to try and compete with real deal stuff and then some jerk can just swipe a design just because he lives in another country. Makes me sweat lead. Especially when real deception is used as is this case. In the future I would check on the manufacturers website for materials used and price asked. When you see a knife with a Manufactuers suggested price of lets just throw out a number $56.75 US then you see a knife on E-Bay that looks like the same knife for $12.99 that should alert you at first glance and make you turn and run the other direction. If you did buy it at least it was a cheap lesson. I hope in the end you are able to get a good deal on the real knife. Shop around, it pays. But shop with the intention of saving 5 to ten bucks or so, but not 45 dollars cheaper. We have a manufactures corner right on this site. I do not know if Extreem Ratio is one of them but it doesn't hurt to look.
My two cents.

PS: I saw where you stated you are Chinese yourself. This could have nothing to do with a Chinese person at all. It could be a ignorant redneck american drawing and selling info to the Chinese. Of course neither is right in doing this. The copying and manufacturing. But what can I say our government is to busy spending money bombing countries and then spending money to rebuild them instead of taking care of it own people and its hard work and patents. But that is the world we live in today. Sad to say.
