Before you throw away a dull knife, try sharpening it with this knife sharpener. You'll be amazed by the return of its excellent sharpness! I've been using this knife sharpener for several years, and it still seems to be in good condition, making it a long-lasting product! This knife sharpener is very compact, but it can perform both coarse and fine sharpening! The knife sharpening function is outstanding. I've tried various knife sharpeners, but this one works just as well as the others I own, restoring the sharpness effectively! Unless you have a professional chef's level ofこだわり (attention to detail), this single sharpener should be sufficient for your knife sharpening needs. As shown in the photo, the usage is simple: just place the knife blade between the sharpening stones and pull it through a few times. After coarse sharpening, perform fine sharpening with the white sharpening stone. The bottom of the main unit has non-slip pads, so the unit won't slip, allowing you to sharpen the knife securely. (The product you will receive is black.) The size is 9.5cm wide x 4.7cm high x 5.0cm deep, so it won't take up much storage space. For this size and price, with fine sharpening included, it's a highly recommended product! If you wish to purchase multiple items, please let me know in the comments. 2 for 1350 yen, 3 for 1900 yen. Since every household has knives, this could also be used as a small gift. It's practical and will be appreciated. Wrap it in gift packaging from a 100-yen shop, and it will make a lovely present! Although it's a new product, there may be very small scratches on the body due to being imported from overseas, but please understand that it's offered at a bargain price. Immediate purchase is welcome. Please also check the profile before purchasing. Due to the thickness of the product, it will be shipped via non-standard mail. Since it will be shipped from the post office, shipping will only be available on weekdays, so please understand.
