The leather string strap has a leather and a canvas side: The leather side is for polishing the knife. The canvas side is for cleaning or targeting the shaving leaf. The ironing strap must be used in advance any shave for aiming and polishing the razor. The tension strap is for the finishing touch and can - depending on the use of the razor - be used once a month. The tensioning belt can also be used as an alternative to the leather string string. In this case, the tension strap must be used in advance each shave.
