This is the 0.1 micron polycrystalline product. The tenth micron product is a 160,000 grit. It is a 100 nanometer particle.
Polycrystalline diamond is more expensive than monocrystalline. It is more friable and has more cutting surfaces than mono. It's main disadvantage is cost, but in many applications it is advantageous in giving the finest level of finish possible, especially in these ultra fine grits.
All of these polycrystalline products are the highest quality and concentration available and guaranteed 100% polycrystalline.diamond - accurately sized for particle size..
The greatest asset of the Kenneth Schwartz polycrystalline diamond spray is the large quantity (10.5 carats) of finely graded polycrystalline diamond particles in the spray bottle. I use bench strops with a very fine nap (such as "Russian" leather) and it’s quick and easy with this product to saturate the napped surface with diamond particles. The negative of this product is no matter what agitation I give the spray bottle,it always sprays with a lot of small "splats" so I haven’t been able to give a uniform spray although these "splats" of greater diamond content don’t seem to affect the ability to refine the knife edge on the strop. I also have polycrystalline diamond aerosol sprays from another source and while I can achieve a very uniform spray pattern with these products,the total amount of diamonds in the aerosol cans is small compared to the heavy concentration of diamods in just a few pump sprays of the Kenneth Schwartz product.
