TechDiamondTools Diamond Polishing Compound Polishing Paste USA Made 3,000 Grit 3-6 Microns for Marble Glass Metal Rock Jewelry Resin Silver Chrome Gemstone with High Concentration of Diamond Powder

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.

I use this on my leather strop that is the last step when I sharpen knives. It is just right for polishing the cutting edge and it lasts a long time before it needs to be replaced. Work much better than the stick rubbing compound I used to use.

Noticeable improvement on blades

I’ve purchased this three times and have been generally satisfied. I use it on leather strops, and as a polishing compound for polishing scratched knife sides. It works well for my needs. I sense that the quantity of diamonds vs. carrier medium is not very high, but neither is the price, so you get what you pay for. I’m my case, I’m unwilling to pay more simply for a higher concentration of diamond dust, and for the price, this concentration of diamonds fulfills all my needs. I recommend it as such.

I have been using this product for about six weeks now on my strops. This stuff is long lasting and its impact is consistent on all my knives. It is a great value for the money and I will be buying more. I use it in modest amounts and it goes aThis stuff is long lasting and its impact is consistent on all my knives.

My backup lens on the Tesla Model 3 has a very soft lens cover and gives a distorted view. After using glass cleaners, micro fiber cloths, other cleaners for exterior cameras I read about using a 2,000 or 3,000 grit polish. In amazon I did my reviews and came across TechDiamond. The polish was the amount I needed and the reviews were good so I tried it. I planned to use a buffer but first I used a microfiber cloth with a pea size amount of the paste. I hand buffed the lens with the paste and it worked! I have not used a buffer only a few minutes of carefully hand buffing. I was so surprised and pleased that this worked and was so easy!!

Just spend the money and buy 1 mic on or .5 micron Stroppy Stuff. Larger than 1 micron is counterproductive.

Knife making family here that prefers this compound for final sharpening needs. It's fantastic and long lasting.

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.

Very good. Works as intended.

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
