Damn that stuff is hard.  Cut down 2 BM CH for local LEOs yesterday, the blade on the saw was done by the time I finished the second CH.  Down to the short strokes on the ends by the time I got finished.  Wish I had taken some pics for the people sitting on the fence so they could see how easy it is.  I was surprised how fast the Al to the aluma-black considering how hard it is.  Two light coats are MUCH better than one thick coat.

Forged aircraft aluminum is pretty darn strong.

It was probably the Hard Anodizing that dulled your bade. Not the Forged Aluminum.

Hard Anodizing can run in the Rockwell C hardness range of 60-90!

Oh yeah. I once nearly ruined a brand-new genuine Sears Craftsman 10" single cut fine mill file recutting the angles on the bottom of an AR scope mount to fit on an AP-74. It was the coating only--once I was through that, it was quick work. NASTY work. Next time I need to do that I'll start with a plastic scope mount.
