Review on 💎 Premium TechDiamondTools Diamond Powder: Perfect for Polishing Glass, Quartz, Marble, Jewelry & More – 3,000 Grit, 3-6 Microns, 25 Carats (5 Grams) – Made in USA! Scratch Remover Included by Jennifer Roberts

This TechDiamondTools diamond powder works great on balsa wheels (I use Sig 3/8" hard balsa 3" wide) and leather (Kangaroo works best on slings). I have 3 grits. On balsa and roo leather it coats my carved chisels and arrow knives and also works great with any good knife or blade. Clean, soft pine from the home center also works in a pinch! (You can pay for the powder by keeping your used Xacto blades - they'll sharpen better than new ones.) Balsa is great for creating special contours for recesses and V-shaped tools. Use some mineral oil to improve adhesion and add the tip of a knife to the lap with diamond powder and work with a belt or lap. Then put a small amount of mineral oil (50% thinner, 50% oil - acetone or paint thinner) in a pump sprayer to make application easier, but spread a few drops of mineral oil over the surface of the powder with your fingertip after the powder has been applied has been worked. when used for a blade or 2 it works too. I use 0.5-1 µm (50,000) for finishing/finishing, 6-12 µm (1500) for general and edge work and 38-45 µm (325) for roughing/repairing. I find the fine powder I use is too fine, it works great but is probably slower than the slightly coarser sand. If you only use one grit, 6-12um is the best choice for more sharpening, cowhide is great for most jobs. Apply only light pressure to avoid pinching the skin and "snagging" the blade edge. Kangaroo skin is firmer and has a tighter face (I understand this is due to the lack of sweat glands) which helps keep the skin from shrinking causing it to wrap around the edge and cause it to sag. In my experience, roo leather is better but quite expensive. Good cowhide leather works great, just be careful how much pressure you use during the finishing touches. This powder has proven to be a great material and keeps going (I'm generous with it, and at these prices it's affordable). . It's a lot cheaper than all the diamond sprays and you end up with a lot more diamonds on your belt. Haven't tried it yet, but I believe you can add it to 50% oil spray and it works well, just shake it before use. I think commercial sprays are nothing more than water mixed with diamond powder so you might as well give it a try. One last tip, this system gives your carbide turning tools a superb finish (even for HSS!), you can give them a mirror finish if you wish, and it pays off in the ease with which they cut and the surface finish produced. Don't forget to polish the top and sides. rough grinding of the carbide with a synthetic resin-coated or coated diamond wheel, then grinding the grains of diamond powder to make a "super cutter" for your lathe (or mill). Grinding enthusiasts will love this powder. Happy sharpening guys!
