The magic test of an imported scratch blade

Over the past year, we have discovered a very strange thing from the purchase records of NBCHAO users. The sales of imported cross-cut blades have exceeded the total sales of all cross-cut knives (whether imported or domestic)! ! !

It's incredible to think about it! Does anyone know how much a razor blade costs? Taking TQC in the Netherlands as an example, the cheap one is more than 1,000, and the expensive one is around 3,000! And a domestic cross-cutting knife (accompanying handle, magnifying glass, brush, "so-called" 3M tape) sold on Taobao for more than 100!

   I can't understand why this is for half a year! Until a foreigner sent this video, after watching it, I understood. Keep it up and see if everyone understands it after reading it. The video is high-definition 30M, about 2 minutes.
