I have a translucent arkansas stone given to my as a gift to sharpen my straight razor. But I don't think it's really doing anything for me (perhaps using it wrong?) so I'm looking into purchasing the Norton 4k/8k stone with the stone flattener that is intended for it.
My question is, for how long can I use this 4k/8k with the flattening stone until it becomes to thin or brittle to use?
thanks.
