Materials:Waterstone made of Aluminum Oxide. (learn more about different materials)
Grit/Particle size: 1000/8000, 14/2.5 micro (learn more about grit)
Size:180x60x28mm (7.09x2.36x1.10 inch)
Weight: about 1.45 lbs
Accessory: Anti-slip silicone base
Well, the 1K side worked fine.
The 8k, not so much.
First it felt softer than the Norton, which was a bit suspicious.
I thought I'd used it to refine the edge after the Norton 8k, since it is sold as 2.5 micron, vs. 3 micron for the Norton.
When I tried to use it after 50 laps or so, the microscope reveal some dents.
I first blamed it on not having set the bevel correctly (which I found surprising as I inspected under the scope the full blade every 50 laps or so). So I went back to 1K and moved my way up when I was sure no micro-dents were left. Extra sure.
Same thing happened again when I try to finish off on that mysterious 8k.
So back to 1K and this time I skipped that last step.
Any ideas what could cause a stone sold as 8k to cause tear in the edge?
