Customer Reviews
Overall rating: 4.9 / 5 from 15 reviews.
PDTools "Expert Pro" sharpening stones are very excellent.
For me, there's nothing better.
I can now sharpen any any steel hardness without any problems and achieve a professional-quality finish.
Be careful, though; the edge becomes so razor-sharp that it can be dangerous for your fingers.
It's an investment, but if you want quality, it's an excellent choice.
I don't regret my purchase.
My stones are:
120 to 500 grit: Hapstone CBN Start
800 grit: Hapstone CBN Premium
1500, 4000, 10000 grit: PDTools CBN "Expert Pro"
Hapstone Top Grain Premium Leather Finish (no polishing compound)
Don't forget to buy a smooth boride dressing stone to clean the stones after sharpening sessions.
