After a lot of testing over 18 years, we finally found the best whet stones.
These German-made stones are sturdy; they have two sides, coarse and fine; 120/240
Can be used with oil for carbide and water for tempered steel.
Green/Grey for tempered steel
Dark/Grey for Carbide
They don't wear out. Your hand and pneumatic flat, tooth chisels as well as
raschetti's will appreciate it.
Each measures 6" x 2" x 1"
