CBN or Diamond?
Both types of stones will make your blade razor-sharp, but CBN (Cubic Boron Nitride) stones work faster than diamond ones. At the same grit size, CBN abrasives leave a smoother scratch pattern than diamonds. This is due to the unique structure of the CBN grains.

PDTools superabrasives stones are suitable for any type of cutting tool:
Kitchen knives, manicure instruments, surgical tools, and many others.
Thanks to our many years of experience, our stones will significantly extend the life of even the most demanding blades.

⚠ Warning! Beware of counterfeits and imitators!
