Thread: How many passes on the naniwa stones

The 12k does cut fast. If you've done your work up to 8k and don't intend to go beyond 12K, ten (MAYBE 15) passes is usually enough. When I use my 12k to bridge the gap between 8k and 20k, I restrict it about 5. When it comes to all grits, its done when its done. But I think you'll find that if you bring a proper 8k edge to the 12k, it won't need much. Just a few passes and you'll see a remarkable difference.
