Oh no, big problem. Think scam. This is one of many fake Japanese knives flooding the market–often sold through Amazon. Almost all of the knives are made in one place in China. There is no tradition of craftsmanship there like in Japan, Germany, or even Taiwan.
You can find all of the knives listed on Alibaba for purchase in bulk. You can probably track this knife down there and determine wholesale offering price. You’ll be amazed! If you think you could sell one to a friend for $40, buy a thousand, start your own label–you could make a fortune!
I have about 14 kitchen knives, held in place by magnets. No slippage–none held on too strong.
