This is a set of a double-sided whetstone (1000 grit / 6000 grit) and a non-slip rubber base. The whetstone combines a "1000 grit medium grit stone" and a "6000 grit finishing stone," allowing you to handle everything from rough sharpening to finishing with just one stone. If you feel your knife's sharpness has diminished, you can easily maintain it with this whetstone and restore it to a state where it cuts smoothly again. As it's a double-sided whetstone, you can simply change the side depending on the purpose. It doesn't take up much storage space and is easy to clean. Durable corundum material is used, so you can use it repeatedly with confidence. Furthermore, using the included rubber base prevents the whetstone from slipping, allowing for safe and stable sharpening. It's widely recommended for beginners and those who want to perform everyday maintenance. 【Product Contents】 ・Double-sided whetstone (1000 grit / 6000 grit) ・Non-slip rubber base Size: Approximately 6cm x 18cm x 3cm Weight: Approximately 800g Material: Corundum 【Please confirm before purchase】 ・Due to being an overseas product, small stains, scratches, or distortions may be seen during manufacturing. ・We inspect the product before shipping, but if a defective product arrives, we will exchange it if you contact us before leaving a review. ・The buyer is responsible for the return shipping costs. ・Returns due to the buyer's personal reasons, such as "it's different from the image," are not accepted.
