Review: Great for stropping cutting tools - Use on leather or balsa - This TechDiamondTools diamond powder works great on a balsa lap (I use Sig 3/8" hard balsa 3" wide) and on leather (kangaroo is best for finishing strops) I have 3 grits set up on balsa and roo leather, it covers my Pfeil woodcarving chisels and knives as well as working great on any good knife or blade. Clear, soft pine from the home center works OK in a pinch too! (you can pay for the powder by saving your used Xacto blades - they will sharpen right up better than new) The balsa works great for making dedicated contours for gouges and V-tools. Use a bit of mineral oil to encourage adhesion and add a knife tip of diamond powder to the lap and work in by using the strop or lap, then add a spritz of mineral oil (50% thinner, 50% oil -- acetone or lacquer thinner) in a pump sprayer makes application easier, but a few drops of the mineral oil spread over the powdered surface with a fingertip after working the powder in by using it for a blade or 2 does the job as well. I use .5 - 1um (50,000) for finishing/fine work, 6 - 12um (1500) for general and edge maintenance work and 38 -45um (325) for roughing/repair work. I do believe the fine powder I'm using is a bit too fine, it works great, but is probably slower than a slightly coarser grit would be. If you only are going to use one grit, the 6-12um would be the pick for most sharpening, on cowhide will work great for most jobs, just use light pressure to avoid compression of the leather and 'hooking' the blade edge. Kangaroo leather is harder and has a tighter face (no sweat glands I understand is the reason) which helps prevent the leather from compressing which cause it the wrap around the edge, causing it to deflect. In my experience the roo leather is better, but pretty expensive. Good bovine leather works great, just be mindful of how much pressure you use during final strokes. This powder has proven to be great stuff and goes along way (I'm generous with it, and for these prices, you can afford to be). It' much cheaper than all the diamond sprays and you end up with a lot more diamond on your strop. I haven't tried it yet, but I believe you could add it to the 50% oil spray and it would work well, just shake hard before using. I think commercial sprays are nothing but water with a dash of diamond powder, so you could try that too. One last tip, this system puts a great final polish on your carbide lathe tools (great for HSS too!), you can get a mirror polish on them if you wish to, and it pays off in the ease with which they cut and the surface finish produced. Remember to polish the top as well as the flank side. Rough grind the carbide to shape with a resinoid or plated diamond wheel, then work through the grits of diamond powder to produce a "super cutter" for your lathe (or mill). Sharpening hobbyists will love this powder - Happy sharpening guys!

## Questions & Answers

**Q: What is the recommended base to mix with this powder to make lapidary paste?**
A: I used water and detergent and a small spay bottle as I'm using it for polishing.

**Q: What method was used to make these diamonds?**
A: This is a synthetic method called high pressure, high temperature (HPHT for short). It's the closest thing to the diamond-producing bowels of the Earth, subjecting graphite (yes, the stuff in a No. 2 pencil, which is made from pure carbon) to intense pressure and heat. Tiny anvils in an HPHT machine squeeze down on the graphite as intense electricity zaps it.

**Q: Can i mix this with thermal paste to decrease my cpu temp by a few degrees?**
A: performance improvements gained from adding diamond based abrasive powder to CPU thermal paste would be negligible, at best. worst case is the possibility of the mix causing performance loss or premature failure of the thermal paste when mixed with another compound. in my opinion it is also not worth the risk of the abrasives causing any damage or wear to PC internals it comes in contact with, intentionally or accidentally. however, there is a usage case for this product in regards to PC component temperatures and performance. water blocks, heatsinks or anything with a mounting surface that one would consider using thermal paste on, can be hand lapped using these types of abrasive compounds for mirror smooth and flat finish. makes it a lot easier to put down as thin and smoooth layer of paste as you possibly can.

**Q: WE make the lapping of silicide and tungsten carbide, carbon, all for mechanical seals. Is this good or do you recomend another diamond powder?**
A: I'm not sure exactly what you are doing or if this helps, but I believe that this grade (4-8 micron) of diamond powder will produce a uniform fine "frosted" look to glass.  The 0-2.5 micron powder removes the frosted (from 5 micron smoothing) when working with glass.
