Like the original Sweeney Todd script? ;)
abrasion, strops
"It is not known when to strop. Original publications report that it should be done before shaving only. Manufacturers found that the microserrations align spontaneously after a day rest as the drawings show. The malaligned teeth may break off when they get in contact with the strop. This might cause embedding of metal particles in the strop, decreasing regularity. Probably, after honing, only the leather side should be used, and in all other cases the canvas first."
Another German source said to
never strop after shaving. Mysteries...
