I've had a bunch of Ruike knives. The Jager is a great example. For the money, especially when it came out, it was a major win. The only reason that I don't use it now, besides owning a ton of other knives, is that I wore out the retention doodad on the sheath. I like it enough that I'll eventually have Kydex made for it.
One of things they had going for them right out of the gate was using 14C28N on the budget end at a time when 8Cr13Mov was the standard and Chinese D2 was still catching on. Now, we're on the tail end of that. Chinese D2 saturated the market for a while but has been (thankfully) in decline. Now, the more popular Chinese brands like Civivi, Kizer, Bestech, Kubey, etc.. have mostly moved on and have embraced decent stainless steels like N690, 154CM, Nitro-V, and 14C28N. On the latter, some of the current brands running a lot of 14C28N, like Civivi and Kubey, are definitely running it harder than on my older Ruike knives. That's not to say that the Ruike knives were bad but they did tend towards the lower end of that 58-60 range and sometimes fell below. It still worked. It was still tough and stainless. It still held a better quality edge than any 8Cr13Mov I've tried and stropped up nicely.
