Thread: Is that a Norway stone ?

Morning everyone !

I have a question today, I've just found this little stone on my flea market, and I'm questioning myself about its nature.

I've heard about Norway stones, really thins ones. Do you think it could be one ?

Some pictures :













She seems really efficient anyway. The slurry comes by itself very quickly, and the stone seems at least as abrasive as a belgian coticule.

Thanks for your help

I'm not familiar with any "Norway" stone.
The most prominent stone to come out of Norway is from the Eidsborg mine.
It was mined for centuries, and is a decent hone for shears and knives.
Here's a link to an article about that stone/quarry. In Norwgian..
The mine is no longer in use, but the area outside of it is still littered with rough cut stones.

I have one other whetstone from Norway that is usable for honing, but that is very dark.
Almost completely black.

Judging from the pictures it looks like Blue Belgian Whetstone(BBW) to me.

Maciek.

No, the BBW's slurry would be violet / red, and this one's pure grey.

I just used the diamond stone on a BBW before lapping this one, so there is maybe a little touch of red on the picture's slurry, but it's definitely not a BBW.

I don't think of it as a french slate (the color would be more like a Dragon Tongue's). Maybe a thin Thuringe ?

The thin stones I was thinking about were Sweden's by the way, but I can't find back the picture I saw that reminded me this one.

Hi Thaeris,

I am not really sure if this is a Norway ragstone. The ragstones do have very small black dots, normally only visible when wet (Last picture). Maybe a view of the hone sides could help to identify.
Here are some pictures of my ragstones:

There is indeed black spots, and when the hone is dry they're not easily visible.

Only got this picture of the side (encountering issues with my camera right now) :



This is the finest stone I've ever met. It's only 0,12 inches thick

A french member of our forum said it could be a "La Lune".

I'd say the grit is around 6000 for this one.

To be in with Thaeris it is possible, from the colouring and the inclusions this might fit, though the inclusions in the Lune stone are mostly less then here...

@thaeris: does it have a reflecting metallic like surface ?

Yes it does !

I don't know its origin but it looks like a very fine grit stone.
