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.

Doesn't really slip on too well.

Doesn't really slip on too well. Also, since the heel is ridged it unintentionally allows my heel to slip out while walking.

Really like these for casual summer outfits
Size: 10.5, Color: White
These are really nice kicks. Stylish, comfortable, and eye catchy for sure. Not too heavy, good price, and fit well. These are great, casual white shoes for a summer outfit. I gave it 4 out of 5 stars as these do pick up and hold onto dirt and smudges more than I’d like to see. Yes, I know, white shoes are magnets for this stuff, but these tend to scuff and discolor more than I would have assumed. I live in an area with lots of bad weather most of the year so I only get a chance to wear them for a few months of the year unless I want to brave the wet and muddy weather. If you live in an area that has lots of sun and are willing to put these to the test and clean them often, I would say go for it.

Bottom of shoes after three weeks worn already have a hole in it! Didn’t expect to have to toss them away so soon.
