Sharpening tips by Tom Blodgett of Jende Industries
Natural stones can often benefit from making a slurry. The slurry is made with a small piece of the same stone, or in this case, a 600 diamond plate.
The slurry is usually white in color, and makes the stone more aggressive out of the gate. This is especially helpful when transitioning from diamond plates to natural stones since the diamonds leave much deeper scratches than naturals.
