NANIWA Lobster Chemical Finishing Stone A3-4 #4000 – Japanese Magnesia Whetstone for Final Sharpening (Base-Free Type)
The NANIWA Lobster Chemical Finishing Stone A3-4 #4000 is one of the longest-selling finishing whetstones in NANIWA’s history, widely used by professional chefs and knife sharpeners.
Made using a magnesia bonding system, this stone requires no long soaking time and can be used immediately with a small amount of water applied to the surface.
The #4000 grit is designed for final finishing, producing a refined and slightly “smooth and controlled” sharpening feel with fine slurry development. It is especially appreciated for Japanese kitchen knives, where a clean yet slightly toothy edge is preferred.
This stone is suitable for a wide range of steels, including carbon steel and stainless steel, making it a versatile finishing option for professional kitchens.
Use after medium grit stones for best results in edge refinement and polishing.
