I picked up the bottom Arkansas stone at a flea market for $2. It appears to have been a longer stone that was broken and reground. It's just under 2" wide, and a little over 4" long.
It's the one on the bottom:

It's not the color of the soft Arkansas that I've seen and know. You can see, I've put it beside my cheapo smith's Soft Arkansas.
It also behaves differently from the cheap soft ark. It cuts much quicker, and leaves a keen edge - better than I can get from comparable grits of sandpaper, or my Japanese waterstone, even. I really, really like it - so much so, I've become interested in Arkansas stones in general.
Is this what many refer to as a "Hard White Arkansas"?
