The Herold Red Strop Paste is a sharpening paste used with strops and bench hones after honing or just periodic touch-up. It has a particle size of 3 microns, and is similar in use to diamond paste, but far smoother, albeit less sharp. After the red paste, finish with a fine Chromium Oxide paste for a sharp and smooth straight edge. Size: .25oz / 8gMade in Germany.
