TechDiamondTools Diamond Polishing Paste Kit — 3 Grits (4000, 8000, 50000) | USA Made | Oil-Based Syringes | Progressive Polishing Set for Metal, Glass, Gemstone, Knife, Jewelry | 10% Diamond Powder

The 4000, 8000, and 50000 combo worked perfectly on my Epoxy project. The original finish had a few bubbles at the top. I sanded first with 50, 250, 1000, 3000, 5000, and 10000 grit sandpaper. Then, I used a wool buffing pad and a medium to high-speed drill with the 4000, 8000, and 50000 grit diamond polish compound. I switched out pads for all 3 grit polishes. I think the 8000 was good, but the 50000 gave it a clear glass look. The only con is that the portions are small, but my project was small, so it was just enough. I definitely recommend this for small Epoxy projects.

I purchased this to create some denim strips for my knives. I’ve tried leather strips but had mixed results and to be fair I may have been using them improperly but even after man my years of stropping with a green compound I got OK results. The knives I wanted to strop were some super blue steel (aogami ) knives as well as a Rockstead CHI knife. Rockstead recommends a denim strop on a wood backing which helps prevent rolling the edge and keeping alignment. The diamond paste came in 5 gram sizes and I used about 2.5-3 grams to cover each strop for the different grit sizes. I used enough to make get 70-90% coverage and spreading as best as I can. The results were fantastic! I took a blade that had done rough spots while cutting paper , it didn’t need to be sharpened on stones , and used the 4000 grit and moved up wiping any residue to prevent contamination. Came back beautifully sharp and sings when cutting paper again. The real test was my Rockstead CHI as I could tell it was a few hairs less sharp than normal but in near perfect condition. I used only the 8000 and 50000 grit. Absolutely factory perfect. Since then I’ve been using it on all my knives and they all get a noticeable improvement even if only doing the 50000 grit. Highly recommended and will be buying more grits.

Expensive and so thick i broke the syringe

This product met all my expectations. It was well packaged and easy to dispense. And worked great on my epoxy resin projects. In fact, I bought a second package knowing I would need (and use) more.

I was skeptical, but I couldn’t be happier with how quick I can put a great shine on projects after finishing with 1000 grit paper.
