Polishing paste

Polishing pastes in different micron sizes (grit)

Micron indicates how coarse the abrasive particles in the paste are. The lower the micron value, the finer the sharpening and polishing. Higher micron values remove material faster and are used when the edge is more worn.

When stropping straight razors, stropping paste in different micron sizes is used step by step, starting coarser and finishing with a finer paste to achieve a smooth and comfortable edge.

• 0.25–1 micron – very fine paste for polishing and final finishing.
• 3–6 micron – fine adjustment of the edge between honings.
• 10–40 micron – coarser paste for restoring a clearly dull edge.

What is carborundum polishing paste?

Carborundum polishing paste contains silicon carbide, a very hard and effective abrasive. It is used when the edge needs to be sharpened quickly and works well as a first step before finer polishing.

When used on straight razors, carborundum paste is primarily a complement to whetstones and finer pastes. After using carborundum, the edge should always be finished with a milder paste or a clean strop without paste for the best shaving results.
