Thanks to its aluminium oxide abrasive, which is less aggressive than diamond, the Thiers-Issard sharpening paste is ideal for delaying the more complex basic sharpening (approx. every 2-3 weeks) a little longer. The paste is used to retain the sharpness for longer and can regularly be applied before each third or fourth shave. Rub a thin layer of paste into the cotton side of a hanging strop or the second leather side of the strop. First "sharpen" on the paste side and then finish on the leather side without paste.
