I had a hell of a time buying a new whetstone for my kitchen knives recently. I didn't want to buy online and I also didn't want to get ripped off. Walmart and Target had nothing but those shitty little widgets you pull a knife through to fuck it up. Home Despot and Lowes only had those and also bizarre sharpening contraptions that included wetstones but also other nonsense to justify bumping the price to north of $50. I finally found what I was looking for, just a regular whetstone with no bells and whistles, for about $3 at harbor freight.
My conclusion is that very few normies care about edge quality and most of those that do are making some sort of hobby out of it and want to buy something excessively fancy. See also Japanese knives; I'm sure they're very nice but two minutes with a whetstone will get any shitty piece of metal sharp enough to cut some chicken. There's no reason to overthink this stuff.
