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.

Looks great.
Love the look. Took a bit to put it together. The only negative was putting on the back with the tack nails. There was no way to see if you were hitting the board so I missed it about 1/3 of the time. Might be better to use wood glue and forget using the nails.

Perfect for a small bathroom
Nice cabinet for the bathroom. I have a 120-year-old house with small bathrooms; this doubled the cabinet space; the white keeps the room visually larger. I'd like to add the instructions are awesome: no verbiage just step by step diagrams. Each hole drilled and ready, as well as pilot hole where the screws will be received. Each piece labeled. The instructions have in the listings the count of pieces with a notation of extra screws, so you don't think you "screwed up" when you're done. One note: as the shelves are part of the construction, they are not adjustable, in my case not a big deal.

Decent product, you get what you pay for
Easy to put together and good price, fit the space we had perfectly. Cheap material, but you shouldn't be surprised considering the price. I saw another review commenting on the difficulty lining up the nails for the back. Wish I would have read it before the assembly as the nails popped through the front side and I had to knock them back and repaint the spots. The directions don't state which size drill bit to use for the wall anchors, but 5/16" worked well. Overall, not great but not terrible either.
