I think it works.
I think it does something? Can't really tell. Any time I've tried stropping a knife after sharpening in the past it's only made it get noticeably duller. This diamond compound seemed to make the bevel a little more shiny without dulling the knife, which is the best result I've ever gotten from stropping a knife after watching about 1000 videos on how to do it. Yaay me.

Smooth Finish, Impressive Results
This 3,000 grit diamond polishing compound completely exceeded my expectations. I’ve been using it on a variety of surfaces—marble, metal, and even a couple of resin pendants I cast recently—and the results are consistently excellent. The paste has a nice consistency that's easy to spread evenly, and it doesn’t dry out or gum up like some cheaper compounds I’ve tried before.What really impressed me is how high the concentration of diamond powder feels. It’s aggressive enough to make a noticeable difference quickly but still refined enough to give a smooth, glassy finish. I used just a dab on a felt wheel and brought a dull piece of silver back to a mirror shine. Same with a glass cabochon—it went from cloudy to crystal-clear in minutes.It’s also nice knowing it’s made in the USA. There’s a sense of quality control here that shows up in how reliable and consistent it is across different jobs. Whether I’m polishing jewelry or sharpening chisels, this compound gets the job done cleanly and quickly. A little goes a long way, so it's also a good value. I'll definitely be keeping a jar of this on hand in my shop.

DÉÇU, j'imaginais mieux
Ja m'attendais tellement bien de cette façon de polir, peut-être mon besoin qui ne se prête pas à son usage, mais pour mon besoin, j'ai acheté 2 barres de métal enduite de poudre de diamant, une FINE et l'autre GROSSIÈRE et j'adore travailler avec ces outils et pour mon besoin, elles me dureront DES ANNÉES
