DMT DiaSpray Diamond Suspension .5 Micron

In spite of all the things written about natural diamonds, staying sharp by fracturing during use, exposing new sharp surfaces, that is hooey. The part they leave out is the part that fractured off isn't dull.DMT are manufactured flawless diamonds, more expensive that natural diamonds, and they do not dull nor fracture/wear away. For stropping it is a rather moot point because the diamonds are not bonded to anything. I like manmade diamonds in the application so my strop doesn't feel second place to the bench stones. (lol) This on a smooth leather strop keep my S45VN pocket knife nice and sharp. A couple back and forthes on the strop on the days I use the knife, has been just getting sharper since the last time I sharpened. I expect going to 6 months between sharpenings based on my early results. Actually sharpens a tad, not simply restoring the edge, is what it's doing for me so far, a couple months in. Followed instructions to the t, 2 or 3 sprays after shaking well on a 3x9 inch strop. Doc guarantees me 35 more years, I won't use half the bottle in that time.

My hobby is (buying and) sharpening Japanese kitchens knives. I use the standard process of 1000 grit stone, then 4-5000, then finish on 8-12,000 grit. All on Japanese or Norton waterstones.To finish the knife edge to my (mildly OCD) perfectionist standard, I strop the knives. For this I use leather, MDF or very smooth pine boards.In all cases, I add diamond paste or spray to the strop. This abrasive is very important, as it removes the very fine burr, and polishes the edge.Of all the diamond products I have used - DMT diamond spray is one of the best. A few light sprays, allow to dry. Works wonders. Polished razor edges.I have seen complaints about the price !! Well - with a superior product, one pays the going price.

Seems ok but can see the lower price equals less diamond concentration it appears as the spray has to go n heavier to notice anything when buffing. Will work just will go thru faster than expected.

Very effective removing all the burr, the sharpness lasts much longer.

Great for getting that perfect edge

The bottle is poorly made and leaks at the cap seal. Much juice is wasted. If you purchase put in a better spray bottle.

The DMT DiaSpray Diamond Suspension is a sharpening game-changer! Its .5 Micron grit delivers razor-sharp edges effortlessly. Easy to apply, versatile, and long-lasting, it's a must-have for maintaining peak cutting performance. Highly recommended!

I gave this 3M product only 4 stars due to the dispenser. Also, just a s a side note, I was under the understanding that the solution would be water based, but it appears to be a petroleum liquid of some sort. The spray bottle quit after one application (10-12 sprays to two strops. After that I had to pull the spray nozzle back up each time. For the money they could have researched the application container a bit more.
