Flatten your stones frequently Flatten your stones frequently No-picture-s Click the pictures to enlarge them

We bought this three months ago on sale at Woodcraft. They go for $32 U.S.

Purpose: A flat reference surface to lap your water stones upon. Water stones sharpen quickly but wear quickly too. Therefore they need to flattened frequently, especially if you are sharpening a thick iron. At 2” the surface plate is thick enough to avoid deflecting under pressure.

To use: Soak wet-dry sandpaper (I like 100 grit), press it down. Lap away. You can also sharpen tools directly on the sandpaper/ plate for a variant of the scary sharp method. I have used it to lap my planes along the diagonal as well.

Cons: It is heavy!

You can also use one of these to accurately flatten the bottom of a hand plane.

Works well for sharpening too – wet 600 grit metal sandpaper sticks well to it and a honing guide and you’re good to go – the large area works very fast. I love this thing and have mostly stopped using my stones.

thanks for the review, i went to a marble/granite custom counter shop i worked across the street from awhile back and they gave me a nice size piece of granite for free the only gripe was the edges. they didn’t finnish the edges the guy asked me if i wanted them finnished but i said it doesn’t matter so i got one with unfinnished edges about 2-1/2’ L x a little over a foot wide and about 2” thick. but i lap my stones on a synder block. i flatten my stones after use so next time i use them there flat always it’s good practice to get into. the granite i will flattem my planes on when i get time to. sorry for the rant.

I have the same type of granite stone and use it to flatten my waterstones as well. I don’t use any sandpaper on the stone to flatten them. Just rub the waterstone directly onto the smooth granite and it will make it’s own slurry and flatten the stone. I have been flattening my 800, 1000, 4000, and 8000 this way. I can’t flatten my 200 grit stone without sandpaper though. That granite stone is money well spent.
