Howdy,
The pitting (flaking) along the bar or tip rail usually occurs because the rail has gotten a raised lip from wear. If the lip isn't dressed back to square, due to hardness, any impact will usually cause a flake or chip to occur.

Thanks for the follow-up.
This bar has a total of about 4 truckloads of Eastern Hemlock on it.
I believe this flake showed up approx. 1/2 way through.
That's only about 6,000 board feet.
I am glad it's on the nose. I looked over the rest of the bar yesterday, and it looks fine.
