I will start using a straight in a few weeks and have decided on either the filly strop or whipped dog poor man strop for my first strop. My question is are both of these ready to go out of the box or do I need to do anything to them before use? From what I've read, I daily strop on the soft side and (many conflicting reviews on this) strop a few strokes on the rough side every 4-7 days to keep the edge. Is this right?
