Balancing it can be done on a nail: you need only that the 2 sides balance, not that the weight-distribution be perfectly-even ( no gunk on the blade while balancing, obviously ).
You want to keep the same kind of angle on the edge as Honda had, & take your time grinding it down if you’re using a powertool for the grinding ( if you’re doing it with a waterstone, you probably want a 80-120 grit, then only bother coming up to 300-400-grit for the edge-finish/microbevel ).
Takes awhile in a single day, & then you’re done for a year.
Take it off the mower, sharpen it, & balance it.

I’m terrible at keeping an angle, so probably just going to get the kit for the rotary. Need the chain sharpener guide anyway.
Jigs exist, for keeping the angle…
I’d wrongly assumed that that would be obvious, sorry.

There are really cheap drill attachments with a sharpening guide, used one for the first time the other week and it works pretty well.
