Thread: Hone ID

Hey everybody.
I'm sure some of you can identify this hone. A friend gave it to me a few years ago. It was pretty beat up and gouged and I left it just sitting around until the other day I decided to lap it and see what it had to offer.
It's interesting to say the least. 2 1/4" x 8" x 1 1/8" Under my microscope it looks very similar to a cnat, but in other aspects it's not even close. I rate it in the 5k-6k grit range based on the scratch patterns it leaves.
The stone is far softer than a cnat. The slurry is very dark gray, almost black. It has a very smooth feel when honing with nice crisp I guess is a good word feedback.
In the pics the stone is lapped to 1000 grit sandpaper.
I'm thinking that it may be an English Silkstone.... Any ideas?
