I've got two of them. Mine are large, long and slow cutting. One slower than the other. I paid a UK vendor $70.00 USD for one shipped and got the other in a trade. They are attractive hones glued to hardwood with a matching cover. All I have seen were cased the same as my two. I have finished a razor or two on them. If you like rocks and want some variety it is cool to have. If you want an efficient razor hone that will not require a lot of laps I would look elsewhere.
