Welcome To a Superior Way to Sharpen!

 They are very hard and produce a pristine edge.  Use a regular psa abrasive, then use my cbn plates and you'll see how far off from the edge you are.  With these you are dead on every time!   You know that even after one shear is sharpened on regular psa abrasives the grit starts to break down.  Imagine, never having a different result.  Always the same grit for years and years.   

CBN grinding wheels grind the hardest materials known to man. CBN is an acronym for “cubic boron nitride” and is the second hardest material known to man, right behind diamond. It has high abrasion resistance and thermal conductivity against high temperatures.

It has a cubic crystal lattice, with its atoms arranged in a symmetrical, cube-shaped structure, very much like the crystalline structure of a diamond. Its material properties include extreme hardness, stability under heat, and superior chemical resistance. 

How hard are they?  So, cbn is not rated in Rockwell hardness.  Its rated in knoop hardness scale.  To put it in prospective, one of the hardest metals is k10 metal, it's rated 93 Rockwell hardness!  But, on the knoop scale it is rated a 17.  Aluminum oxide abrasive is rated a 16 and silicon carbide is rated a 17.  CBN however is rated at 30-32.  Way harder than anything you are going to sharpen.  And way harder than any other type of abrasive you can use, except diamond of course. 

CBN grinding wheels are far safer than conventional grit wheels. There are no harmful chemicals that come from CBN.

Minimal sparks. Minimal sparks are created when grinding, which makes for a safe user experience.

No dust. No dust clouds are created when using these wheels. However exhaust ventilation is always recommended when grinding.  Any dust will be coming from the shear and not from the wheel.

Minimal heat. Little to no heat is produced using these wheels.

Easy clean up. When you are finished grinding, simply use a magnet to clean up grinding debris.

 They are the coolest running abrasives.  No burning!  They stay cool throughout the whole sharpening process.  This leads to longer life with your edge.  (note: they can heat up some if left on the plate for an extended period of time)  

My wheels are lifetime wheels.  They will outlast any other type of abrasive, even Diamond.   Free yourself of PSA pads for life! 

These wheels are made to order and will fit on every kind of flat hone and many other types of machines as well.  

CBN is better than diamond for sharpening shears.  Diamond grits glaze over and can melt under high temperatures.  It happens.  CBN is much better with handling the type of heat produced from sharpening shears and keeps the shears cooler.
