Thread: Scratch Patterns

But as others have said, it's a pretty poor diagnostic and lots of things can cloud the issue - things like the type of abrasive particulate and the shape of the scratch it leaves, and how that shape reflects light back to your eye. A sharp particulate like diamond chip may leave a "V" shaped scratch, whereas a more obtuse particulate might leave a flatter "U" shaped scratch, both at the same depth say. One may well look worse than the other under reflected light.

I dunno, that's just random thoughts. Sounds pretty good though, right?

I dunno Dave, I was about to ask him what the h*ll he was talking about Just that I didn't quite get it, not that James is full of it.

I kindof stop looking at the loupe after my last stone... I'm also guessing that the higher the magnification, the greater the temptation to "overthink" it. I've got a basic 30x. When I got it, I was doing two steps forward and one step back for a little while there.

Did you decide what to do with the 3/8k?
