Artisanal Japanese kitchen knives are all up, for obvious reasons, but the Yuki skyrocketed. It was popular because it was affordable, stainless clad white #2 with an okay handle. I think that popularity juiced up the price, which sadly defeats the purpose.

That bunka is a fantastic knife for under $100. I paid $150 for my Yuki gyuto, which was a legitimately good deal even at the time.
