Review: Unbelievable results! Using a small amount of this on a soft micro-fiber cloth I polished the mineral glass crystal on my Garmin Instinct Crossover Tactical watch and it is so clear now that it looks unreal, or not even there. I guess you never know how many small scratches it gets until you do this - results like getting a new windshield in your car. Review: I purchased 6 microns (3K grit), 1 micron (14K grit) and .25 micron (100K grit) to be used as compound for strops. I purchased the 50% concentrate. I tried this diamond compound with really tight and smooth leather (feels like kangaroo tail), balsa wood and basswood. Basswood will be on a fixed angle system, which will be soon. This is what I have experienced so far: * The 50% is very aggressive, do not let the high grit fool you. Cuts and polishes very fast. * Use a very light coat on strops, like in the pic. Light coats take 24-48 hours to fully dry on leather, 36 hours on wood. For those 2"x6" strops in the pic I only used 0.2 grams per strop. Using a very thick credit card to spread across the strop. * The 6 micron was way to aggressive for what I wanted, can dull your knife if you do not keep the angle. Recommend a hard strop surface to prevent rolling of strop surface to not dull your knife. * Keep the angle or on a fixed angle system that has a stone compensator (to keep the apex angle) stropping will help to refine edge and further minimize micro burr, after main de-burring techniques. Use very light strokes, even the .25 and 1 micron is aggressive. * Off of a 1000 grit diamond stone, stropping 1 micron then .25 micron will give your edge the look of a 5K - 6K finish. A am speaking of minimal stropping. * Way more effective and aggressive than green or white rouge compounds. And much simpler to apply to a strop. * Lastly I do not recommend using for stropping before it is fully dried. You will be moving the diamonds from the surface of the strop when still wet and make the compound not as effective. ## Features - OIL-BASED COMPOUND: we offer 1 item 5 gram syringe of industrial quality diamond polishing paste with 25% concentration of diamond powder, professional grade of 100,000 Grit, 0-0.25 Microns which is most suitable for Final Polish. - MADE IN USA: Forget other cheap polishing compounds!

For deep scratches, trying to remove them is not screen functionality safe. However, the same kit will help to make those scratches less noticeable. **Q: What kind of oil do you use? Can I use this on a leather strop?** A: We use oleic acid. But if you need to loosen the compound up, you can add practically any machine or motor oil to it. Yes, it can be used both on leather strop/cloth and on wool cloth. **Q: What is the significance of the concentration? Wouldn't the grit be the same regardless of how much powder is in the compound?** A: From my understanding, it would be like 100 grit sandpaper with only part of the sand on it. Yes, it's still 100 grit, but there isn't as many granules of sand, which would make you use more and it would take longer. This paste worked extremely well on polishing my tungsten carbide ring. **Q: how would you load a leather stope with this?** A: I'm not sure if I'll get this right, but I'd dispense a fair amount onto the strop and rub it in evenly. This is an oil paste , so you should get an even coating. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***N on 20 February 2026* Unbelievable results!

When I held the pliers horizontally and released the lower handle to gravity the jaws would not open 100%. I combined small amounts of WD-40 and 100,000 grit (0.25 micron) diamond paste in oil in a shallow empty glass container. I used a tooth pick to stir these ingredients (about 10 minutes) until a homogenous slurry was made. I added a brief spray of WD-40 to achieve a consistency that was "right" - no lumps, not too thick, not too thin. I applied the slurry to the fulcrum and rubbing surfaces using a Q-Tip and set the tool aside for about 10 minutes to allow the slurry to penetrate spaces between the surfaces. I then worked the handles for an additional 10 minutes after which the jaws would finally open completely once the lower handle was released to gravity. (I performed the same process with my Tsunoda pliers but it required 70 minutes time to achieve the same results.) I then sprayed the fulcrum and rubbing surfaces with WD-40 to flush the slurry from the tool. I wiped the tool with a rag, applied more WD-40 to the fulcrum and rubbing surfaces, worked the handles again for about 30 seconds, and cleaned the surfaces with a rag. I allowed the WD-40 to evaporate (about 15 minutes), removed any remaining surface residue with a rag, reapplied light machine oil to the metal surfaces, and set the pliers aside. After 30 minutes I wiped excess oil from the pliers and placed them in my tool box. ## Frequently Bought Together - TechDiamondTools Diamond Polishing Compound Polishing Paste USA Made 100,000 Grit 0-0.25 Micron for Marble Glass Metal Rock Jewelry Resin Silver Chrome Gemstone with High Concentration Diamond Powder - SHARPAL 162N Double-sided Diamond Sharpening Stone Whetstone Knife Sharpener |Coarse 325 / Extra Fine 1200 Grit | Storage Case with NonSlip Base & Angle Guide (8 in. x 3 in.) - SHARPAL 204N Leather Strop (Genuine Cowhide) 8" x 3" Kit with 2 Oz.
