I would say "no". 3Cr13 and 420J2 don't really "sharpen". You can buy a Sanrenmu with 8Cr for $6.
The whole copying thing with SRM and Ganzo are certainly legit when we talk about patented features like Axis locks. SRM has gotten away from Axis locks. But let's put the copying thing in perspective:
HK knives are made by Benchmade, and SRM. You'd think Benchmade would be more put out by that.
Schrade copied the iconic Buck 110 decades ago, and people just love that copy.
Schrade recently copied a Chris Reeve design.
Microtech copies other US companies, but charges 40x what a SRM or Ganzo do.
So I get the issue, but I don't get why $10 knives are so upsetting when SRM and Ganzo represent the least profitable examples of this behavior. Why is Microtech even in business when their products are sold pretty much to knife collectors who actually care about these distinction.
I realize I'm bordering on fanboy with the SRM products, but after growing up with Gerber and Buck plastic lockbacks, dealing with quality issues on SOG and owning too many Spydercos and Cold Steel knives that aren't made of anything nicer than AUS-6, the four SRM knives I've owned have been such a pleasure. Good steel, centered well, mechanism works well and looks good. Most of the ones I've bought are completely original SRM designs.
There seems to be a real bias on this forum that seems to be based on "truisms" like "you get what you pay for" that are no longer true. Buying a quality product directly from the source country is a culmination of the US consumer behavior that destroyed the US manufacturing base and emptied rural America of small retail. We have screwed ourselves in our desire for cheaper and cheaper consumer goods - so we might as well enjoy our $10 knives. We've earned it.
