Humor on this jon,
Ive done this for 5+ years.
And it worked really well for me all this time.
The angle you usually sharpen the blade.
Start at the tip, angle/grind in .
make multiple steps in the opposite way the bean counters made the current angle's.

I have multiple sets of mower blades. Always a set sharpened ready to go. While my yard is more field than lawn and harvests rocks and roots, my blades last a few years. Usually they wear thin where the ear turns up at the rear of the blade. The leading edge is sharpened to match the factory angle and stays reasonably nice. I sharpen 2 or 3 times a mowing season. When the ear breaks off, the blade is discarded due to the out of balance vibration. I have not tried cutting off the remaining trailing ear and then rebalancing. I purchase blades on sale at the end of the mowing season,

I guess I don't follow.

I have been buying Stens blades the last few times. Always bought Cub Cadet blades before, but seems like the OEM changed the blade and I didn't like it. When I sharpen, I put a shallower angle than the manufacturer did. Stays sharp longer with a longer edge. I hope that made sense. I've never balanced blades, never had a vibration. Guess I am good at sharpening, I don't know. Not really much science to it, not to difficult a job.

On my new Walker Mower, the blade speed is relatively slow, so the blades need to be sharp. They are somewhat a special blade, so currently I use OEM. That mower has been doing its job like clockwork. Just about ready for an oil change again. Nearly put 100 hours on it already.

I did the exact same as you Jon, but I reversed the angle along with the notches (multiple short angles on each cutting end).

You ground the angle on the bottom of the blade? I'm not following....

Lol, nope.
I reversed the angle from the way cc's selling them.
They stopped selling blades years ago that was squared off then sharpened, that you always knew.
I'm grinding multiple steps/angles on each end.
and sharpening each as i go.
