We have posted enlarged photos as much as possible so that you can see the condition clearly. If you are considering a purchase, please take a close look at the photos and be sure to ask any questions or point out any concerns before you buy. Please note that if you discover any defects after your purchase, you will not be able to cancel the transaction. Therefore, please contact us before completing the transaction. Thank you for your understanding. *We have not used this to sharpen blades. We have listed it based on its shape. (Compared to the whetstones we are selling separately, this one is finer and smoother.) Please take a close look at the photos and make your own judgment.
