Lobster A3-2 Fine Sharpening Stone - #4000



Naniwa manufactures superb Japanese waterstones intended to sharpen knives. What makes these waterstones unique is that they don’t require soaking prior sharpening, unlike the conventional Japanese waterstones. Just sprinkle a little water to the surface and you’re ready to sharpen!


Japan made Naniwa stones are consistently graded, from their #220 grit to #12,000 grit stones and work with hard steels like A2 or D2 as well as other stainless alloys. Naniwa stones are resin-bond made. Resin-bond allows higher level of roughness resulting to quick sharpening and does not need soaking.     

We highly recommend these waterstones from Naniwa!

Size: 210 x 70 x 22mm 

Use & Precaution 

This stone does not require soaking. Sprinkle a little water only when sharpening. As a general rule, never soak stones with #3000 grits and higher in water. After use, let the stone dry thoroughly. Returning a stone into its box while still wet or damp will result in molding and might decrease in quality.
