This is true of a lot of product types, but there is often a QC process that happens for the "premier" name brand that they were manufactured for. And these "duplicates" are frequently the irregulars that didn't make the cut.

In the case of knives, they may be perfectly fine. Or QC's spot testing of that batch may have revealed defects in the metal, and a small number of them may shatter unexpectedly.

This is why I'm fine buying some categories of items from AliExpress et al., and not others.
