I should point out that the honing guide for straight razors is built into the razor.
With the spine on the hone the angle of the bevel is ideal for shaving and razor steel.
Use little or no pressure, razors have a thin flexible edge so pressure changes the angle
often in undesired ways.
A razor that is correctly sharpened can be touched up on a 12k hone.
Ten to twenty hone strokes, strop and shave test. Repeat next week as
if needed.
