Double-sided knife sharpening stone set (400/1000 and 3000/8000 grit), large size, newly manufactured, precise grit size, 210*70*22mm, non-absorbent,

【Great Value Premium 5-Piece Sharpening Stone Set】This product is a set of five sharpening stones with different grit sizes: a #180 sharpening stone for flattening, a #400/#1000 double-sided sharpening stone, and a #3000/#8000 double-sided sharpening stone. This set can handle almost everything from coarse sharpening to ultra-fine finishing, depending on your needs. The #180/#400 is a coarse stone ideal for repairing chips and nicks and restoring sharpness; the #1000 is the most convenient medium stone for daily maintenance; the #3000 further refines the sharpness; and the #8000 achieves mirror-like sharpness and beauty. Furthermore, it includes upgraded non-slip rubber, a stainless steel all-purpose sharpening stone stand, and an angle fixing guide, making it a significantly better value than purchasing the stones individually. *Please note that this set is not suitable for ceramic knives or non-metallic blades such as titanium.

【2026 New Manufacturing Method - Accurate Grit Sharpening Stones】Sintered sharpening stones have significant problems with grit size. We frequently hear complaints about issues such as "coarser than the number indicates," "wrong grit," and "reverse grit." Therefore, we've introduced our new pour-molding method!!! This highly precise whetstone minimizes the difference between the grit number and the actual grit size, and we've paid meticulous attention to the grinding feel and texture, making it highly recommended for beginners and those who prioritize a high-quality finish. 【No need to soak in water - Non-absorbent whetstone】One of the advantages of our new pour-molding method is its non-absorbent design. Instead of soaking the whetstone in water for 5-10 minutes before sharpening, simply rinse it lightly with water before use – incredibly convenient!

【Easy-to-use, larger size whetstone】We often hear that our conventional 180 x 60 x 30mm double-sided whetstones are a bit difficult to use due to their small size. As a solution, we've designed a larger 210 x 70 x 22mm whetstone. Compared to smaller whetstones, it's easier to apply pressure to the blade stably, and the sharpening feel is significantly improved compared to the old model. Furthermore, the large surface area of ​​the whetstone significantly increases sharpening efficiency, making it perfect not only for regular knives but also for long knives, large knives, and other knives with a large surface area to sharpen.

【True Double-Sided Whetstone】Currently, almost all commercially available double-sided whetstones are made using a sintering method, resulting in inaccurate grit sizes. Whetstones with accurate grit sizes usually only have one grit size per stone. To solve this problem, we produce whetstones using a casting method with accurate grit sizes, and then use adhesive to create double-sided whetstones. As a result, we have double-sided whetstones with accurate grit sizes! Compared to commercially available double-sided whetstones, the grit size is more accurate, making them safer to use. Compared to single-grit whetstones, for the same number of stones, our whetstones offer a greater variety of grit sizes.

【Quality Inspected】Our knife whetstone sets are rigorously inspected at the factory, undergoing durability and functional tests in the kitchen. In addition, before shipment, we also conduct inspections by a third-party inspection company. *Due to the long shipping distance, problems during transit are more likely to occur. In such cases, please feel free to contact us. We will arrange for a replacement or other appropriate action without any complicated procedures.
