I haven't seen waves like that develop during finish grinding yet, but right at the edge you'll sometimes get some metal that's paper thin and starts to ripple. Maybe you've almost ground through the blade near the center?

Regardless, that's a fantastic first effort. Heck, it would be a good 10th effort.

Keep at it!

The edge curled at the very end of the grinding. I was using a 600 belt wet, to clean up and bada bing I have a pringle. I said blue words. I measured all over with the micrometer. The grind is pretty consistent, that is unless I have a valley that is smaller the anvil on the micrometer.

The grind looked pretty consistent before heat treating.

Thanks for all your guys help and encouragement. I have learned a lot from this forum.
