A woodworker sells these bits of Welsh slate he processes on Ebay, and estimates they are roughly equivalent to about an 8000 waterstone ( He also has higher grits) At about a third of the price of a cheap Japanese waterstone 8000 grit. Could be worth a look, no? So mine arrived today, and I needed a sharp chisel for a work in progress, so - Attachment: Repair 3.jpg New Ashley Iles 1" chisel, worked the back up through the diamond grits 400/1200/8000. Then went to the Dragon's Tongue, worked up a slurry with the supplied rubbing stone, and started polishing the back. It's a bit slow, but seems not bad at all, and is certainly a higher grit than my DMT 8000. And it of course gave a better edge than I got with the DMT 8000, even though it's been quite well used for a few years after breaking it in with a Stainless Steel block. Have look yourself - what do you think? Attachment: Repair 4.jpg I don't need this fine an edge all the time, but it's good to have available when you need it. |

I don't have that particular stone but I do have a slate stone that someone gave me a few years ago. As you said, it cuts a bit slower than an 8,000 waterstone. It's not as slow as my Arkansas though. I think you could do a lot worse than Slate for use as polishing media, especially at the price. This isn't too bad either: http://www.amazon.co.uk/Kitchen-Master- ... ss+diamond My first dip into diamond stones. I like it. I like it a lot. Just depends how long it lasts. I've been using it regularly for 3 months and so far it's still cutting well. That and the slate is probably all that is required. Somehow I've ended up with far too many stones. |

I use a set of 3 of these, admittedly I often stop on the 8000ish one, but I like them. Sent from my D5503 using Tapatalk |

Pretty dang hard, and doesn't break down relatively easily like japanese waterstones when making a slurry (although they vary quite a bit) http://www.infotile.com/pdffile/advicetopic/34201054307.pdf Have a look at Table 6 Welsh slate is about the hardest slate around. So, between the hardest marble and quartzite/basalt, (or the lower end of granite) |
