Narrow your glass selection and use standard bevel down hone, wire edge
removal order. The bevel will lie flat with light pressure, especially as
it is pretty long.

Or get a stone. Old boys here used a scythe stone with bark knives. Of
course, that's a bit rougher work than I put to my knives.

Sorry if this seems novice. I use sandpaper on plate glass to sharpen my
plane
irons and chisels. Obviuosly the handles of the drawknife would be in the
way.
Do you have to buy stones and drag it across them? How do you keep a
consistent edge? Thanks for answering.
