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.

This sunscreen body lotion is quite nice.
Style: Piña Colada
This sunscreen body lotion seems to work well. SPF 30 is the highest I could find with moisturizing capabilities. The smell is a bit overwhelming when you first put it on but it then goes away... so why the added scent. I wish it were SPF 50 and unscented. Otherwise I would have given it 5 stars.
