Afraid of being sandwiched by 180 knives

$M provides a reference for the competition. Considering the 30k brushed today, the actual is 180k, with wear approximately 145 dollars. This is still under very good control on my part. This M fluctuates by 2 dollars, and that's for the lowest wear. If it's higher, it's directly 20 to 30 dollars. I do not recommend participating; if you're stubborn, just go for it.
