## Features

- Double Side Flattening Stone: This innovative Flattening Stone is different from any other flattening stone in the market. It is a two-sided, dual grit, diamond grid flattening system designed to produce excellent flat surfaces on sharpening stones. Built from high-quality silicon carbide the flattening stone particles help in cutting sharpening stones material precisely. This makes it ideal for flattening as it cuts quicker and wears slower making it extremely strong and durable
- Unique Design: Specially designed Diamond shaped grid pattern of the grooves quickly and efficiently removes only waste material while flattening any type of Sharpening Stones, Whetstones, Oil Stones or Ceramic Stones
- Extra Large Size: Our double-sided whetstone flattening stone has an extra-large total flattening area. Making it 3X times bigger than any other stone on the market & large enough to completely flatten any whetstone.
- Dual Grit: The 120 grit(Dark Grey) side is used to flatten coarse water stones with 900 grit & lower, this side provides the necessary cutting action to effectively flatten the stone. However, when flattening finer Waterstone, a coarse grit leaves a finish that you may find undesirable. So we have designed #320 grit(Light Grey) side for water stones with 1000 grit and higher
- 100% Satisfaction: Not all Whetstone Knife Sharpeners are created equal. We only source premium quality material for the manufacturing of our Whetstone which will provide superior cutting performance

## 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. There will never be a time to flatten the flattening stone. Use course/mediums (less than ~600) on the course side and all fines (more than ~600) on the fine side

**Q: How flat is this "flattening stone" ?**
A: This flattening stone is flat and did a great job flattening an old sharpening stone I had laying around for years. It’s worth the price.

**Q: Can I use this flattening stone on a whetstone 12000**
A: I would ask the seller to be sure but I think you can by using the fine side ok

### ⭐⭐⭐⭐ Sharp Pebble replaces defective Stone and the new one works excellently.
*by K***R on July 17, 2020*

I recently bought the Flattening Stone from Sharp Pebble after having been very impressed with their other products. I used the FS on a small waterstone and was very happy with the results, it cleaned it up very quickly. That said, I was surprised to see that the FS has been worn down significantly. I had planned on using it on many of my older stones but realized it would be gone in no time if it wore in the manner it did with the first stone. I contacted Salma at Sharp Pebble with my concerns and she was very helpful. She explained that the FS I received must have been defective and replaced it with a new stone. The new FS arrives and worked perfectly with almost no visible wear. I would give the new FS 5 stars but because of the issues with the first stone, I’m staying at 4 stars. Sharp Pebble is awesome.
