@onebadwolf Your post reads as if you haven't even watched the video or if at least listen to what he said.
It's clearly stated that the unmarked knife is not made by CH knives, the other ones with markings were correct, except of the Fura for $20. Easy summary, you get what you pay for, no need to hope for D2 with 60HRC for 20 bucks but the more expensive ones (bought at trusted shops) are all legit.
