The Naniwa (Lobster Brand) 1000 grit waterstone is the most commonly used grit waterstone. This stone is intended for daily maintenance and establishing an edge on a dull knife. Needs to be soaked in water (usually until the bubbles stop) before use. Learn More

The Naniwa Stone Holder secures your stone while sharpening or flattening. It has good traction with the rubber mounts and sufficient weight to keep from moving around. Holds stones from 5.5 to 9 inches in length.
This is good quality stainless steel that won't rust out on you. We tested one leaving it in the water overnight and pulling it out in the daytime as we used it. Other models rusted on us within days. The Naniwa never rusted after two months, and the screw downs still move smoothly. Now, these shouldn't be left in the water and we're not suggesting that. But if it gets accidentally left in the soak tank, it's not going to be a problem. Learn More

Dimensions: 11.8 in x 5.9 in x 0.8 in  24 grit Coarse carbide stone Promotes maximum cutting for all grit sizes of whetstones. Produces extremely flat results on all water stones, ceramic or traditional. Flattener and stone should be wet before use. This large flattening stone comes with rubber feet and is designed to be laid flat in a sink bottom while you hold the stone and run it across the flattener. Extra coarse for fast cutting. We use these because of the high volume of hand sharpening. This cuts quickly, but can leave fine grooves in the higher grit stones, which should be smoothed with your dressing stone. For persons doing a more normal volume of sharpening, the large 220 grit provides the benefit of truer flat without the grooving, it just takes longer. (Most flattening stones are around 220 grit) Learn More

Achieve the Legendary 'Scary Sharp' Mirror Edge Sharpening is a journey that begins with repair and ends with refinement. For those who demand more than just a functional edge, the Naniwa 10,000 Grit Ceramic Super Stone represents the pinnacle of Japanese abrasive technology. Unlike lower grits that remove steel to create a new edge, this ultra-fine 10,000 grit stone is a specialized tool designed to polish and temper. At this microscopic level, you are no longer 'grinding'; you are aligning the steel's molecular structure and removing the invisible burrs that prevent a knife from gliding through delicate proteins. The result is a 'mirror edge'—an aesthetic masterpiece that provides a frictionless cutting experience. Crafted using Naniwa’s proprietary resin-bonding process, this stone offers a unique tactile feedback often described as 'creamy' by professional sharpeners. This ensures you can feel the angle of your blade across the surface, providing more control than harder, glass-backed alternatives. Whether you are maintaining a high-carbon Honyaki or a modern VG-10 blade, this stone delivers the final, definitive touch of sharpness. Learn More
