I knew I had something American somewhere but I couldn't think what. When I checked on the Wilton drill press vise I recently imported from the US, it turned out, now made in China, but made well nevertheless.
Then I remembered my little hard translucent Arkansas sharpening stone collection.
The one at the top right is the 'oldest' probably dug out about 100 years ago...Pike brand taken over by Norton/Bear. Its the best of the lot but they either mined all of that stuff out years ago or the mines with that grade of stone are now in parks so they can't get to them, I think I read somewhere.
The yellow one below it is dated 1963 on the box. Not too bad but not as closely grained as the one above it. The grey one at the bottom is probably a Norton anywhere from 25-35 yrs 'old'. Norton still sell those stones...just, but they are quite a lot chalkier and less transluscent, from what I can make out.
The darker grey one on the left is a large Norton slip stone and that is quite old, possibly late 40's or pre-war.
The little white slipstones to the top middle are new. Not too bad...quite translucent and glassy ie not too chalky.
There used to be loads of mines, now only a handful. Good pre-war mined hard Arkansas stone is very hard to find now and going up in value. Personally I love the stuff....I don't think anything on earth has been found to equal a good Arkansas for putting a razor sharp polished edge on a tool.
And a good hard Arkansas will never stain, wear down or need to be dressed.
