Quote: "hit a sweet spot of quality, price and demand."
The price missed the "sweet spot". In the beginning ( ~ 2005 ?) the prices were $5-$10 and more recently they have crept up a little but still are under $20.
I began buying RR knives in 2007, at first just to see how bad a $5-$10 knife would be. To my great surprise all were very decent, sharp knives. Every other knifer i told about the RR knives dismissed what i said because it seemed impossible to sell anything but 'crap' at that price.
It took years before enough knife knowledgeable people had tried the RR knives such that the collective positive opinion took hold. Had the price been higher (e.g. $20-$30) i think they would have caught on much earlier.
You can still buy a new RR for under $10 delivered to your home address. Even if the knife was acquired for free in China i still do not understand how $10 covers shipping to USA, then shipping within USA, warehousing, marketing and USPS delivery to the buyer.
