TLN’s video is emphasizing the cutters used in a scraping plane. These are typically sharpened by creating a dead square edge around the profile.
The original poster is asking about a plane with a bedded iron so it has a profiled bevel.
As this is a beading plane, it is pretty easy to sharpen and even restore a damaged blade, short of severe damage to the quirk cutting portion.
Using an appropriately sized dowel wrapped in grits of sandpaper is a good start. Glue on the sandpaper so you can then put the dowel in a vice. Angle the dowel so that you match the bevel and thus hold the iron dead horizontal or dead vertical during the sharpening and honing. This works well for an iron that has been damaged. Once you restore the bevel shape (check it against the shape of the plane sole) you can stick with honing.
You can free-hand hone using slip stones (black Arkansas ones are good and not terribly expensive, just don’t drop it). Or you can take the blade after using your highest grit of wet-dry (1,000 or 1,500 maybe) and use the plane to create a profile in some hard wood. Pick good clear grain and work the right direction. Go slow and take light cuts. You now have an exact shaped hone. Rub on your green compound crayon, remove the iron from the plane and draw it back across the profiled hone (at the right angle of course).
Polish off the back again and enjoy.
