This dual-grit flattening stone re-levels any waterstone, oil stone, or ceramic stone fast: most users flatten a badly dished stone in about 5 minutes and rinse it off flat as new. - DUAL GRIT DOES COARSE AND FINE - ONE TOOL Use the 120-grit side for coarse water stones (900 grit and below) where you need aggressive cutting, and flip to the 320-grit side for fine stones (1000 grit and up) so you don't scratch a premium finish. No guessing, no second tool, no changing sandpaper. - FULL 8-INCH SURFACE FLATTENS ANY STONE At 7.99" x 2.79", the flattening area is large enough to true a full-size whetstone in one pass instead of working it in sections — faster, more even results with less effort than compact flatteners. - DIAMOND-GROOVE PATTERN CLEARS THE MESS AS YOU WORK The diamond-shaped groove pattern channels away slurry and waste while it cuts, so the abrasive keeps biting instead of clogging. Tip: work at the sink under a light water flow with a towel handy — the slurry builds fast, and rinsing as you go lets you see your progress and speeds up the job. - PREMIUM SILICON CARBIDE — CUTS QUICKER, WEARS SLOWER Built from high-quality black silicon carbide chosen to remove material fast while holding its own surface longer than soft flatteners. Backed by Sharp Pebble responsive support — if anything arrives less than flat, we make it right. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B082YH4HTZ | | Best Sellers Rank | #33,940 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #42 in Sharpening Stones | | Brand | Sharp Pebble | | Brand Name | Sharp Pebble | | Color | Gray | | Customer Reviews | 4.3 out of 5 stars 1,560 Reviews | | Grit Type | Coarse, Fine | | Included Components | Large Flattening Stone | | Item Dimensions L x W x H | 7.99"L x 2.79"W x 1.1"H | | Item Highlight | Restore Any Sharpening Stones, Oil Stone & Ceramic Stone in Minutes - Extra Large 8" Diamond-Groove Silicon Carbide | | Item Weight | 1.6 pounds | | Manufacturer | Mighty Dreams | | Material | Black Silicon Carbide (Japanese Quality) | | Material Type | Black Silicon Carbide (Japanese Quality) | | Model Number | SP120320 | | Number of Items | 1 | | Number of Packs | 1 | | Product Dimensions | 7.99"L x 2.79"W x 1.1"H | | UPC | 658848369645 | | Unit Count | 1 Count | ## Product Details - **Brand:** Sharp Pebble - **Color:** Gray - **Grit Type:** Coarse, Fine - **Item Weight:** 1.6 pounds - **Manufacturer:** Mighty Dreams - **Material:** Black Silicon Carbide (Japanese Quality) - **Number of Items:** 1 - **Number of Packs:** 1 - **Product Dimensions:** 7.99"L x 2.79"W x 1.1"H ## Images ![Flattening Stone - Dual Grit 120/320 Whetstone Flattener - Image 1](https://m.media-amazon.com/images/I/71hUg6fxl7L.jpg) ## Questions & Answers **Q: Can this be used to re-flatten a damaged chisel grind edge on a chisel or flat grind knife?** A: Absolutely not. This is a honing stone flattener not a honing stone. **Q: How do i keep my flattening stone flat. what grits do i use on each side??** A: Just using it re-flattens its surface each time.
