White corundum, one of the hardest minerals in the world, is attached to the base made of tempered glass in the Taida Glass stones. This type of sharpener wears much slower than traditional water stones, you do not need to soak it in water before use (just spray it with water) and most importantly, you can use the sharpener to the end, because the glass prevents the stone from breaking even if the abrasive material is a few millimeters.
