This Combination Whetstone has been specially developed to provide a 'single-stone solution' for repairing small chips, 'thinning' blades and correcting other blade geometry issues. It can also be used to create a surprisingly sharp, 'toothy' edge, or for shaping the cutting edge before honing and polishing with a Shiage Toishi (仕上げ砥石 ,"finishing stone").
Our first "JCK Special Combination Whetstone #1000 / #4000 Grit" has been very well received as a basic, daily use whetstone, which allows you to regain a fine cutting edge on all different kinds of blades and cutlery steels. However, because our customers may also need to use a coarse-grit stone to maintain their knives in 'original condition', or may want customise the blade geometry of their knives, we have decided to also offer the "JCK Special Combination Whetstone #400 / #1200 Grit".
This new combination whetstone has a Coarse-grit Whetstone (Arato / 粗砥) on one side and a Medium-grit Whetstone (Nakato / 中砥) on the other side. The high-quality abrasives that we have selected for our new coarse and medium grit Combination Whetstone provide a powerful cutting action and will allow you to carry out important blade maintenance and blade geometry correction procedures (Such as correcting uneven blade grind, correcting blade profile issues, 'thinning' the blade, or removing small chips in the cutting edge). Carrying out these procedures will allow you to get the best performance from your knife and allow you to enjoy your knife for a long time. We recommend that you either use the coarse-grit side of the whetstone to sharpen and 'thin' your knife occasionally, or, alternatively, use it every time you sharpen.
The #1200 medium-grit Nakato side of the whetstone is extremely versatile and can be used to either refine the scratches left by the coarse side of the whetstone, or to create a surprisingly sharp, 'toothy’ edge that is ideal for cutting meat and many other ingredients.
Coarse and medium grit whetstones are the most popular and useful whetstones in Japanese home kitchens. If you are considering a first whetstone, we recommend starting with our new #400 / #1200 grit combination whetstone. Later on, when you find the need for a more refined edge, you can purchase an additional fine-grit finishing whetstone, such as our "Super Fine #6000 grit Whetstone", our "Super Fine #8000 grit Whetstone", or our versatile "JCK Special Combination Whetstone #6000 / #10000 Grit".
We believe that the "JCK Special Combination Whetstone #400 / #1200 Grit" will be a great addition to your sharpening toolkit because it will allow you to keep your knives well-maintained, ready to perform perfectly. The stone is proudly marked with the JCK logo and comes with a complimentary non-slip rubber sheet/pad. You can place this sheet underneath your whetstone to prevent it from moving whilst sharpening, or to prevent it from scratching the work surface.
Before sharpening with this whetstone, please soak it in/under water for approximately 10 minutes (Until air bubbles stop coming out of the whetstone). To ensure a smooth and efficient sharpening experience, we recommend that you occasionally re-wet the surface of the stone during sharpening.Before storing your whetstone, please air-dry the stone in a cool, well-ventilated area, away from direct sunlight and other sources of heat.
