100% pure chromium oxide mixed with a little oil to make the ultimate strop paste.
Rather than removing metal, stropping with chromium oxide smooths, polishes and refines the cutting edge; not unlike the effect water has on clay.
Chromium Oxide (Cr2O3 ) is a superfine, 0.3 micron, polycrystalline abrasive, it is the mineral that gives green polishing compound it's colour. Most polishing compositions also include other minerals, but for purists like straight razor users, only the best will do.
The most effective way we've found to apply the paste is to apply a very small amount (pea sized) with a butter knife in a very thin layer across the leather. We sometimes add a drop or two of mineral oil to slacken off the paste slightly to make sure you can get that layer nice and thin.
For most people this 50 gram tub will be a lifetime's supply.
Works like a charm, if you don't believe me, ask your barber.
