Dupont Polycrystalline Heavy Concentration Honing Spray - 0.25 Micron
Professional chef testers are reporting that our new diamond honing spray to be the best that they've ever used. It's said that it refines and creates such a sharp keen edge that they don't feel the need to use as many sharpening stones or even sharpen as often. Many sighted edge retention was increased dramatically to decrease the need for waterstone sharpening.
Dave Martell says, "In my own testing, with over 30+ diamond spray types reviewed, I can say without hesitation that this diamond spray is the very best that has ever passed through my hands or has been sold by us to be used on Japanese kitchen knives."
Expensive Dupont polycystalline white diamond particles are held in a water based suspension that comes packaged in a convenient spray pump bottle. The diamond particles in this solution are held in suspension through the use of a binding agent.
Unlike less expensive monocrystalline diamond particles, polycrystalline diamond has self-sharpening properties which continually release worn and dull surface monocrystallites to expose fresh sharp new cutting edges below. This occurs even moreso with this particular diamond spray because of a special Dupont process that micro-fractures each particle to crack under stress. For this reason, Dupont Polycrystalline diamond spray will hone and polish faster than any other diamond spray.
This is the finest quality diamond spray/slurry available on the market today. This product has been tested and approved by us specifically for use on Japanese knives.
Best suited: For use on the textured leather bench hone that we sell. Not suited for all leather types - may cause drying. Use caution when used with felt as it will bubble felt up if too much is applied. Use VERY sparingly on felt honing pads.
Directions: Apply a coating to leather pad/strop or felt honing pad but take care not to soak as damage to pads may occur. I suggest using a layering approach much like you would use while spray painting. Apply several light coats versus one heavy coat.

said (of the Dupont Polycrystalline Diamond Honing Spray):
"Edge retention is phenomenal. Beat it up for a week now and it's
holding to about 85-90% of its edge fresh off the stones. If it starts
to lose anything at all 5 or 6 passes on the pad will bring it right
back. I use the pad every morning before I start and that's all it
needs; it will hold all day until the next morning. Chock full o' bite
it sure has."

First I'll admit that I was a bit of a skeptic about
the new diamond spray+
leather, but after using it I've become a believer. My edges do feel
after stropping on the new setup, as compared to the CrO on smooth that I
using before, and the leather really does show where the burrs are.
