HELP! Best chipper blade sharpener

[Kitcuts]

I am looking for some advice if anyone else sharpens their own chipper blades. What system do you use? My employer purchased a grizzly, universal knife sharpener, and I’ve tried to get super low grit stones for it. I found some at 60 grit and I’ve got some from Amazon that are 30 grit, but it really doesn’t seem to do a great job of sharpening them quickly. You can’t make much progress. It takes about 30 minutes per side to get them to be one cohesive sharpening thank you very much.

We use an ancient Michigan Knife Company planer/chipper knife sharpener from the 80s or before (I guess I’m showing my youth by calling that ancient). It’s similar to this on that sold on auction except ours doesn’t have the auto feed. This is not a fast machine either, and sharpening can take a while, especially if there is a huge gouge in a blade. https://www.laibids.com/auctions/31154/lot/171362-michigan-industrial-knife-grinder-model-36af
