Jointer / thickness planer knives sharpening jig

I saw this method and wanted to check if it really works. My Jointing / thickness planer is a Holzstar ADH 305 (not sponsored) and lately doesn’t cut as well as it should.
After the sharpening, the knives didn’t become as sharp as a razor blade, but it improved the finish on the wood.
Thank you for watching.

As I can guess, this is some Holtzstar planer. What was the angle of the blade bevel?

You are right, it's a Holzstar ADH 305. Don't know the blade bevel angle. Just tried to copy the existing angle. The blades turned out sharper, so it kinda worked.
