Whetstone Flattener

Availability: Normally ships the same day

 This Whetstone Flattener is another useful tool to have in your knife sharpening kit. After repeated use, the surface of your whetstone will become uneven, and this unevenness will make it difficult for you to maintain a uniform sharpening stroke and  a consistent sharpening angle. The only solution, is to flatten the surface of your whetstone.

 This Whetstone Flattener is our recommended way of flattening your whetstones because it has great grinding power and is ease to use.

 If the surface of your whetstone is very uneven or dished, you can use the grooved side of the Whetstone Flattener to flatten your whetstone. This side provides more grinding power/pressure and will allow you to quickly flatten your whetstone. Subsequently, you can use the flat side of the Whetstone Flattener to make the surface of the whetstone completely flat.

 The Whetstone Flattener can also be used to smooth and round-over the sharp corners and edges that your whetstone will develop once it has been flattened. This is an important maintenance step, since the sharp edges can cut your fingers. This procedure will also prevent the edges of your stone from breaking apart during sharpening, which can lead to large scratches or nicks in your cutting edge.

 We sincerely hope that this product will make your sharpening jobs more enjoyable and allow you to more easily regain the original sharpness of your Japanese knives.

*Please Note* : This Whetstone Flattener needs to be soaked in water for approximately 10 minutes before it is used (Until bubbles stop coming out of the whetstone).

My first flattener

I didn’t realize there were sharp casting lines around all the edges and ended up putting quite deep scores across my water stone. I flattened the flattener by grinding the edges down and eventually got most of the scratches out of my honing stone. It should come with a warning about this.

Received exactly as pictured, but didn't use it yet, still using my previous stone.
