It's a cutter à la chinoise from Banggood, actually my first Banggood purchase.
It's quite the prettiest cutting tool thing I have ever seen!
I get it that such colours, like as seen in soap bubbles, or camera lens coatings, or on a bit of metal heated, are all about the thickness of the transparent coating in odd numbers of quarter-wavelengths. In the last quarter-wavelength, the thinnest interfere blues and violets, leaving yellow, and so on.
I guess they work and wear out like any other, unless that coating is amazing!
I just think the colourful stuff adds something to the appearance among steel surfaces and chips
