A real Kramer is often much, much more than $2,500. Kramer’s mid-line knives go, even used, for $10–$30K while his high-end, rarer stuff goes for much more. In fact, Bourdain had a real Kramer with meteorite used in its construction that sold at auction in 2019 for $231,500.

So they are not real knives then, just rich boys play things?
