Description
The Nagura Sharpening Slurry blocks are essential accessories for serious sharpening. Available in two formulations—Fine and Extra Fine—they are designed to condition whetstones, improve slurry formation, and enhance edge refinement.
These blocks are used by gently rubbing them over the surface of a whetstone that has already been moistened, just before sharpening. This action generates a controlled sharpening slurry, a thin paste of abrasive particles that helps evenly polish the blade, and keeps the stone surface clean and active.
-
The Fine Nagura Sharpening Slurry is best used with whetstones up to #4000 grit. It helps clean metal deposits from the stone, prepares a smooth abrasive layer, and encourages uniform wear.
-
The Extra Fine Nagura Sharpening Slurry is intended for high-grit stones #6000 and above, where it refreshes the surface, enhances polishing, and aids in achieving a refined kasumi finish without introducing visible scratches.
Using the correct Nagura slurry not only speeds up sharpening but also prolongs the life of your whetstones and ensures more consistent, professional results.
