I’m wondering how people can recommend a worn/used Koetsu for a person you said his budget is $500 max???
No, you're not wondering, not at all. You're just trying to take a cheap shot. Nobody recommended a Koetsu. I said buying used opens up a lot of options and mentioned one example I have seen.
You can convince yourself of your cleverness but the plain fact of the matter is the more you twist the truth around to fit your predetermined narrative the more you undermine your own credibility. Do it enough you risk sounding like just another MDS crank.
