Has anyone had experience with repairing their bent & cracked blades? I've already tried the search engine, so this does not need to be a rant on not climbing with pole saws. Thank you.

I think you need to charge more.

Are you for real?
hi there cliff,there is nothing to be done.a bent or cracked blade will Always re bend or crack in the same spot,everytime.buy new,hence "charge more".and before you might ask,sharpening, unless you hav alot of spare time, is wasted time.last thing,given your choice always buy tri-cut blades.they last a bit longer and cut better,but cost a bit more.And a good 16' pole has saved many a climber time and effort in both setting ropes over short distances,and pruning out at the tips where the bulk of your pruning should be done,instead of a zip and strip.a pole however, is NOT a trade off for the knowledge and practice of how to get there in the first place!

No, I don't but sometimes if it's just the tip, say a couple inches. I just cut it off with a grinder. Matter of fact my hand saw is that way right now.
Sure. Easy to bend or weld, if you are good at metalworking. It's probably not practical, though.
Work any bends with a hammer on an anvil to correct the bends. Then try heating the bend area with a propane torch until it glows, lightly tapping out any remaining bends imperfections (bright cherry red is bad!). Then reheat to the same soft glow and quench rapidly in oil. Then reheat to 400° to remove stress. Resharpen any affected teeth.
If that doesn't work, buy a new one. All you are out is the expense of the propane to heat the steel and your time to play.

I've straightened out my Longboy blade a few times but they're pretty thin. I forgot it was hanging from my belt today when i came out of tree and bent a 45 degree in the blade. When I straightened it it cracked so it's new blade time.

No, Blades are cheaper to replace than anything you would do to save a buck.
I forgot to clarify: if you have bent the blade so far that it is breaking when you straighten it, heat before you try to correct the bend. Those things break because they are so hard and springy. Heating removes the temper. Reheating and quenching restores the temper.
The factories do the heating and tempering with automated processes and very controlled situations. Tough to reproduce without all the sophisticated equipment. Although...the Japanese were doing it hundreds of years ago in simple blacksmith shops.
